6.7 Cleaning system and valve
If sand or other particles has entered the system, you can clean the system and the Valve,
following the instructions below:
- Clean the Inlet Hose and Mesh Filter so that there are no sand particles in Inlet Hose and
Mesh Filter;
- Connect the Mesh Filter to the Inlet Hose and the Inlet Hose to the Villagepump (check
carefully if everything is connected well;
- Put the Mesh Filter in the water (as clean as possible);
- Dismantle and remove the UF membrane (1) - see par. 7.5 of O & M manual;
- Start pumping up the water (without the UF membrane mounted);
The water should now come out of the valve. Most water will come out from the most upper
hole/connection of the 3 holes/connections that connect the UF membrane(3).
If the water is running out of the valve, the system cleans itself.
- After a while (5 minutes), block the upper connection by putting your hand in front of the
connection to stop the water, so the water should come out of the other connections. Pump
for another 3 minutes. Now the Valve will be cleaned (4).
- Replace and connect the UF membrane.
