5. Plumbing, basic rules
•Use shower & bath water as source water and optionally washing machine water in case a
Hydraloop washing machine recycle option is installed. No washbasins, kitchen sinks &
dishwasher may be connected!
•Before connecting the back up mains water supply to the Hydraloop unit, first let this
water run for some time to flush sand and dirt out of the mains water tube before
connecting it to the Hydraloop unit. If sand or dirt enters the Hydraloop unit this will damage
the the internal pump and valves.
•Connect all incoming greywater pipes into a single 75/50/40mm pipe into the 40mm inlet on
the top of the Hydraloop unit.
•On the low side of the Hydraloop, for connecting the recycled and treated water:
•use the left hand ½” flex hose and connect to the tube that feeds all toilets
•use the right hand ½” flex hose and connect to the washing machine, and
•In case of a Hydraloop Pool/Garden, use the single ½” flex hose and connect to the tube
that feeds the garden rainwater tank or feeds the pool
•Label everything. Use color coded pipe or warning labels on the pipe to designate that the
pipes are running recycled water
•Hydraloop has a built in overflow facility
•Install appropriate overflow at the sanitary liftpumps to avoid flooding the systems
•Standard plumbing practice should be performed. The 75/50/40 mm greywater feed tube
from the shower/bath needs to have proper ventilation to support shower water flowing
without airlocks to the Hydraloop unit. Also sewer venting is necessary to ensure proper
functioning of the Hydraloop unit.
•With the washing machine recycle option installed, the wastewater tube from the washing
machine needs to be"fed into the Hydraloop system via its sanitary liftpump. Even in the
event the washing machine is installed on a floor above the Hydraloop unit, the water still
needs to be fed via the liftpomp - controlled by the Hydraloop unit - with an overflow to the
sewer. The sanitary liftpump receives 230 volt grounded current from the Hydraloop unit and
is switched on/off by the Hydraloop unit. The overflow is used to discharge the first 2 washing
cycles to the sewer when the liftpump is switched off.
Overview of Hydraloop plumbing options (see drawing on next page)
•A. Greywater flows by gravity from shower & bath on 1st floor to the Hydraloop unit on the ground
floor.
•B. Greywater is lifted up using a liftpump* from shower & bath on ground floor to the Hydraloop
unit on the ground floor.
*We recommend a DAB Novabox or Genix VT030. It is important that the pressure tube from the lift pump is
32mm to avoid excessive flow of water entering the Hydraloop unit.
•C. Greywater flows by gravity from shower & bath on 1st floor to the liftpump on ground floor to
the liftpump, and is then lifted up into the Hydraloop system.
•D. Shows how the washing machine should be connected via its dedicated liftpump that is
delivered when opting for the extra washing machine recycle option with your Hydraloop unit. The
dedicated washing machine liftpump is powered and controlled by the Hydraloop unit.
Note; assure that appropriate venting is installed as shown on the drawings.
