I Have Black Bits In My Water System?
If the caravan is fitted with a Carver Crystal water filter it should be replaced during the caravan’s annual service. If you have black bits coming through your taps it is usually because the filter has broken down and released its' carbon into the water system. You will need to replace the filter and flush the system.
If you have a pressure switch this will also have to be cleaned out for it to work correctly. To do this, follow these steps.
1. Remove the pressure switch from the caravan.
2. Undo the 2 screws from the inlet and remove the inlet tube.
3. Push the non return valve out and remove the ‘o’ ring to allow the non return valve to be removed and cleaned.
4. Run some water through the pressure switch to remove the carbon from the diaphragm.
5. Reassemble the pressure switch.
Before refitting the switch, remove the clear plastic top from the old filter and refit it into the filter housing. Put the inlet tube in a bowl and run the pump to remove the carbon from the filter housing. Refit the pressure switch and test. The carbon may keep coming through the taps for a while, but will stop after a few gallons of water have passed through the system.
Black bits from the toilet flush
Add a dose of Milton steriliser to the fresh water tank and leave for up to 12 hours then flush through several times to clear any residual debris.
