5.1 Pumping up water first time and first backwash cycle
If the Villagepump has been installed, the Pump Handle mounted and the Mesh Filter is in
the water, you can start pumping. Depending on the length of the hose (and if the blue fork is
on the first or second or third hole of the lever), it takes some time before the first water is
coming out of the tap.
Note: at the start you will only pump air and this will take some time, especially when
the hose is 10 meters or the distance to the water level is higher than 3 meters. We
recommend to open now and then the dispense unit at the Valve (Black Screw Cap)
and leave out some air during this procedure. Also during the first backwash some
water/air will come out the system (tap/drain). However after one or two back wash
cycles the air will be out of the system.
Open Screw Cap of the dispense unit of the Valve at first time pumping up water to release the air.
- When you start pumping, the pressure indicated on the manometer will slowly advance to
about 2,9
– 3,6 bar. In normal use, this will take about 5 - 10 minutes or producing 30 to 40
litres of water.
Manometer, indicating the pressure of the Back Wash Buffer (collecting the water for the back wash)
- Once the pressure has reached in between 2,9
– 3,6 bar, the UF membrane is
automatically flushed, the so called "backwash". At the moment of backwashing, you will
notice that the indicator in the manometer is falling and water is flushed with great power
through the drain hose.
- Please note: do not pump during backwash. Although not harmful for the system,
water will leave the system via the pressure relief valve indicated at the picture below.
