I have a Whale water pump in my motorhome I went to bed and found the carpet was flooded. I discovered that the pump filter housing had failed and was leaking water. The next day I tried to reseal the filter housing with high quality sealant but with no joy as when it was under pressure the water found another place to leak from, we had no running water for the rest of our holidays.
I would recommend buying two of these filter housings as they can be unreliable and are cheap to buy
