S23 WATER PUMP

[hg2016]

Good afternoon all. Long time since I've been on the forum. I hope everybody is well.
I have a Sealine S23. When working properly the water pump pulses and water flows from the tap at a steady stream. Lately it seems to be pumping out lots of air and spluttering and when I turn the tap I can often hear the pump humming in the background and I have to turn the water pump off at the control panel. The water flow from the shower head in the toilet does seem little bit weaker than usual. This has been going after quite a few water tank re-fills.
Any help will be well received.

I have had similar issues recently which seem to clear with use... it takes a while for air in the system to escape.
Check the pressure relieve valve on top of the calorifier and try releasing some air from that.
I suggest cleaning the filter on the pump inlet and replace the O ring when you refit the filter. Look for any slight leaks from the pump .
I replaced O rings a couple of years ago and it brought the pump back to useful life but they don't last forever

Thank you. I'll give that a try. I assume the water pump is in the engine bay.

In a S23 I believe it is in the engine bay .
I owned a S23 6 years , changed it in 2014 for a F33 - but same make and model of domestic water pump.
