Pre-installation checklist
Our pre-installation guidelines are detailed on the following pages, but some of the key
“do’s and don’ts” are highlighted below:
Do’s
Locate the pump next to the hot water
cylinder OR no further than 4m away in
22mm pipe work
Allow 100mm on all sides for ventilation
Ensure pump is protected from frost
If servicing two or more bathrooms, cold
water supply to the cylinder must be in
28mm pipe work
Ensure adequate cold water storage
(50 gallons/bathroom, 80 gallons for
one bathroom and one en-suite)
Cold water supplies to the pump must
be taken from the opposite side of the
cold water storage tank to the cold
water mains inlet
Multiple cold water storage tanks must
be linked in 28mm pipe work and the
bottom of the tanks must be at the
same level
Hot water supply to the pump must be
via a Salamander approved flange
AV couplers must only be finger tight
plus one quarter turn
The maximum static head should be
10m (equivalent to 100kPa/1.0 bar
pressure) – only exception is the
RP50TU which is 5m (equivalent to
50kPa/0.5 bar pressure)
We recommend the pump is activated
for at least 5 minutes every 4 weeks
Don’ts
Never fit the pump to the cold
water mains
Never fit the pump to communal risers
Never use a shared water supply
Never put a non-return valve (NRV),
inverted loop, restrictive balofix or an
air vent on supply pipe work to the pump
The hot water supply to the pump must
not exceed 60ºC
Never twist the anti-vibration (AV)
couplers or bend more than 35º
Never use mechanical tools to tighten
coupler nuts as this may cause damage
and will invalidate your warranty
Never use jointing compounds,
Boss White, Hemp or steel wool
Solder fluxes must not come into
contact with the pump or AV couplers
Never install in a bathroom unless in
an enclosed space and access is only
possible with an appropriate tool
Never pump directly to or from another
pump
Never connect to a secondary return
tapping on a hot water cylinder
BEFORE INSTALLATION OF YOUR NEGATIVE HEAD
PUMP:
Please fit the pressure vessel if packaged seperate
to the pump. Use the ½ “ at rubber washer in the
½ “ brass connecon on the top of the pump juncon
box. Screw the pressure vessel into the connecon hand
ght.

PumpWise and warranty
1. Location of the pump
The best possible location for the pump is
at or near the base of the cylinder at least
600mm below the bottom of the cold water
storage tank. Where it is not physically
possible to locate the pump next to the
cylinder, the pipe run from the hot water
cylinder to the pump must not exceed 4m in
22mm pipe work.
1.1 Cooling and ventilation
The pump should be placed in a position
where there is an adequate air flow to cool
the motor and separated from any other
appliances that generate heat. It should be
installed in a clear space allowing 100mm
additional space at each side, the ends and
top of the pump.
1.2 Frost protection
Loft mounted pumps must be protected
from frost damage.
2. Hot and cold supplies
to the pump
Never fit the pump directly to the cold
water mains.
Never fit to communal risers (e.g. block
of flats) or secondary circuits that are
pumped.
The pump must be fed by exclusive hot
and cold water supplies (i.e. not shared
with other services) and in 22mm pipe
work (Note: for the RP50PT and RP50PS
a maximum of 2m of 15mm inlet pipework
direct from the cylinder to the pump).
The hot supply pipe work should be a
maximum of 4m from the cylinder in 22mm
pipe work.
All up and over pipe work must be vented at
Please follow these installation instructions carefully. Failure to install your pump in
accordance with these instructions will invalidate your warranty.
the highest point on the outlet of the pump
and a non-return valve (NRV) may require
fitting to the hot outlet only (Note: this is
only for the RP50TU and RP55SU).
2.1 For pumps positioned above the
hot outlet, hot water cylinder or in
a loft
An anti-gravity loop (AGL) off a No stop
Essex Flange must be used when it is sited
above the dome of the hot water cylinder
as it prevents air tracking up into the pump
chamber and back siphoning of the water
again, creating air in the pump chamber.
Never put a non-return valve, inverted loop,
restrictive balofix or an air vent on the
supply pipe work to a pump.
Where the pump is servicing two or more
bathrooms, the cold water supply to the
cylinder must be in 28mm pipe work.
2.2 Cold water storage
Ensure that the cold water storage capacity
is adequate for all of the household
requirements (minimum 50 gallons/227
Litres per bathroom, 80 gallons/385 Litres
for one bathroom and one en-suite shower
room).
Ensure the cold water supplies to the
cylinder and the pump are taken from the
opposite side of the cold water storage
tank from the cold mains inlet.

The hot water supply to the pump must be
via a Salamander approved method:
The best hot connection from the cylinder
is either
• A 3⁄4” NO STOP ESSEX FLANGE. See
Figure 3 or
• Alternatively a Salamander S flange or
other approved top entry flanges. See
page 15/16.
• Never fit to top entry flange if the pump
is fitted above the cylinder.

General specification
Trouble shooting
PumpWise and warranty
The plumbing installation must comply
with “The Water Supply (Water Fittings)
Regulations 1999” and “BS EN 806-
4:2010” buildings regulations.
5 Electrical requirements
The pump must be connected to the
electrical supply using the mains cable
with the attached plug. This plug must be
connected to an accessible socket that has
been installed in compliance with BS 7671
(I.E.T. Wiring Regulations). The plug must be
accessible at all times.
The pump must not be installed in a
bathroom unless it is installed in an
enclosed space accessible only with the use
of a tool.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified person in order
but they must NOT be twisted or bent more
than 35º (this invalidates the warranty).
See Figure 5 above.
Each single pump is supplied with two
couplers; one angled and one straight.
The angled coupler should be attached to
the pump inlet (on the side) and the straight
coupler should be attached to the pump
outlet (on the top).
Each twin pump is supplied with four
couplers; two angled and two straight.
For all pumps, the inlets are on the side of
the pump and the outlets are on the top of
the pump.
The AV couplers MUST only be tightened
to finger tight plus one quarter turn.
Mechanical tools must NOT be used to
tighten coupler nuts as this may cause
damage which will invalidate your warranty.
4 General plumbing
The installation must comply with the
relevant requirements or local by-laws.
The pump MUST be mounted upright (shaft
horizontal, not screwed down).
Jointing compounds, Boss White, hemp
or steel wool MUST NOT be used. Solder
fluxes must not come into contact with the
pump or AV couplers.
The maximum static head should be 10m
(equivalent to 100kPa/1.0 bar pressure)
with the exception of the RP50TU where
the maximum static head should be 5m
(equivalent to 50kPa/0.5bar pressure)

Right Universal Pumps - system operation and
L.E.D. indication
Right Universal pumps are designed to protect
customers by responding to unexpected and
unforeseen conditions. Right Universal pumps
will only be switched OFF if the unexpected or
unforeseen conditions are serious.
Right Universal pumps capable of:
• Supply water temperature sensing
• Dry run protection
• Sensing chronic aeration or water starvation
• L.E.D indication of unforeseen system malfunction.
IMPORTANT NOTE
The HOT and COLD pump ends are
identified by RED (hot) and BLUE (cold) tie
System malfunction is indicated by three
L.E.D’s located on the top of the pump
junction box. see Figure 9.
NON RETURN VALVES MUST NOT be fitted
in the discharge pipework between the
pump outlets and the system outlets
unless specified by Salamander Pumps.

Figure 11: Positive head
Negative head systems
Negative head systems exist where no
natural flow of water goes to the outlet
because either the outlet or the pipework
to the outlet are above the height of
the base of the cold water cistern. Most
instances of negative head systems occur
in loft conversions or where the cold water
cistern sits on the joists in the loft. If the
distance between the bottom of the cold
water cistern and the highest point of the
system after the pump is 2 feet (610mm)
or less, it is also possible that a universal
pump will be required. Salamander’s
universal range of pumps activates the
pump automatically even where no natural
flow exists.
Negative head is also needed for electric
showers, dishwashers, washing machines or
where pumped hot water meets mains cold.

Commissioning
Before you nish
• Flush inlet pipework and carefully fill
pump with water by discharging water
from the outlet flexible coupler into a
container.
• Fit pump inlet filters.
It is CRITICAL to discharge water through
the pump into a container using natural
flow before connecting the pump to outlet
pipework in order to ensure the air has
been discharged from inlet pipework and
pump chambers. This will not happen if the
outlet pipework is connected to the pump.
The best method is:-
Figure 19
• DO NOT RUN PUMP DRY – to do so will
cause irreparable damage to your pump
and will invalidate your warranty.
• Open shower mixer valve/system
outlets to maximum hot and cold to
check the natural flow (unpumped) flow
of at least 1 litre per minute – positive
head systems.
• Open hot water outlets fully for
5 to 6 seconds and then turn outlets off.
Then open cold water outlets fully for
5 to 6 seconds and turn outlets off. If
flow is poor and inconsistent repeat
above steps until flow is steady.
• Repeat 2-3 times.

Recovery of cold storage
The typical recovery rate of a 1⁄2 inch high
pressure part II BS1212 ball valve is:
100 kPa (15PSI/1.0 bar) 0.97 galls/min 4.41
200 kPa (30PSI/2.0 bar) 1.34 galls/min 6.11
270 kPa (40PSI/2.7 bar) 1.58 galls/min 7.18
400 kPa (60PSI/4.0 bar) 1.94 galls/min 8.82
Aeration of pump and cylinder from a
cold water storage tank
This occurs when the incoming cold mains
ball valve is positioned above the cold
feeds to the cylinder and to the pump –
aerated water is drawn into the pump as
illustrated.

Chronic aeration of the pump occurs when
this problem is combined with inadequate
storage capacity and/or when the volume of
water drawn by the pump and other services
exceeds the refill rate and creates a vortex
which draws air and possibly debris into the
pump.
Cold storage usable capacity
The usable capacity of cold storage is
easily calculated as the capacity of water
in the cold tank above the cold feeds to the
cylinder, the pump and other outlets –
see formula.
Formula for calculation on rectangular
tank:
Depth (15”) x width (23”) x length (36”)
= 12,420 cu inches
Volume cu inches (12,420) x 0.01639
= 203.56 litres
Volume litres (203.56) x 0.22
= 44.78 gallons.
Formula for calculation on circular tank:
Depth (15”) x radius (17”) x radius (17”)
x 3.142 (Pi)
= 13,621 cu inches
Volume cu inches (13,621) x 0.01639
= 223 litres

= 49 gallons.

Water starvation protection, pipework arrangements and stored hot
water
Water starvation protection
In systems where it is absolutely not
possible to increase the usable cold water
storage capacity to meet the increased
demand of a pumped system; a water
starvation protection unit (WSP) may be
considered.
The WSP is a Salamander level switch which
must be positioned 102mm higher than the
highest outlet from the cold water storage
tank. When the water level drops too far the
WSP will switch off the pump until the cold
water storage level is recovered.

An anti-gravity loop (AGL) must always
be fitted to systems where the pump is
positioned above the hot outlet from the
cylinder. The AGL which limits aeration
of the hot supply to the pump is formed
by bending the pipework downwards for
250mm, as it exits the Essex Flange, before
rising again to the pump. See Figure 26
overleaf.
Please be advised due to lack of cold water
storage with Elson and Fortic (type) tanks,
our pumps may not be suitable.
It is advisable to contact our Technical
Support team before installing the pump
on 0191 516 2002, otherwise it may
affect your warranty.

Combi boilers and water heaters
As these appliances are invariably supplied
directly from the cold mains – they are not
normally suitable for booster pumps. The
exceptions are featured in Figure 14 on

Approved anges (cylinders)
The 22mm No Stop Essex and the other
approved top entry flanges with extension
pipes into the cylinder represent the best
known means of ensuring minimal aeration
of the hot supply water to the pump. The No
Stop Essex flange is in all circumstances
the best option.

B The supply connection to the pump
MUST BE FROM THE TOP of the Warix
Flange via a 22mm compression elbow
and thereby avoid inverted loops.
C In systems where there are one
bathroom and an en-suite shower.
Or two or more bathrooms the cold
feed to the cylinder MUST be in
28mm pipework.

Inverted loops
An inverted loop in the supply pipe-work
to the pump, particularly on the hot side as
illustrated; is likely to:
• interfere with the initiation and smooth
operation of the pump.
• restrict the supply water to the pump
and risk internal mechanical damage.

Primatic cylinders and Andrews type
water heaters are not suitable for pumped

Water hammer protection
Water hammer most commonly occurs in
systems where there are long pipe runs
supplying solenoid activated appliances
e.g. washing machines or outlets with quick
acting/turn taps/ valve(s). The harmful
effect of water hammer shock waves can
be cushioned by fitting a pressure vessel
unit, into the supply pipework as close as
possible to the outlet from which the shock
waves are originating.

Pump hunting protection
In negative head systems all the discharge
pipework after the pump is pressurised. In
such systems there exists the possibility
the pump will hunt ON-OFF-ON etc at
intervals.
This will happen:
• if all outlets are not fully closed
• if there is a leak at a connection
• if boosted toilets are not fitted with
equilibrium ball valves
• or as residual hot water contracts in
long pipe runs.
The irritating effects of hunting are
cushioned by the pressure vessel which is
an inbuilt feature of Right Universal pumps.
Stored hot water volume
In calculating the volume of the stored
hot water requirement it is important to
consider:
• number of bathrooms, with particular
attention to the size of the bath
• number of persons in household
• time spent in shower e.g.10mins in a
5 gall/minute shower will use up 50
galls/227 Litres of the cold water
storage capacity approx 60% of which
(30 gallons/136 Litres) will be hot water
from the cylinder.

hot water system it is recommended that
the stored water temperature is controlled
independently from that on the primary
circuit”.
Extract from BS6700:1997
“Under normal conditions the
temperature of stored hot water should
never exceed 65°C. A stored hot water
temperature of 60°C is considered
sufficient to meet all normal requirements
and will minimise scale deposits in hard
water areas”.
Effective control of stored hot water
is simply achieved by use of a cylinder
thermostat and zone valve or direct acting
thermostatic valve (e.g. tapstat).
In systems where the stored hot water
temperature is not controlled eg Aga solid
fuel appliance or very crudely by the boiler
thermostat, use a HWS Blending valve
controller.
