I recently bought a used older
boat. The fresh
water system
pump has seemed a bit sluggish lately. This morning one tank was dry and when I switched
tanks still nothing. The
pump runs for quite a while before stopping. But when the faucet it opened, some
water comes out, a burst, then a trickle, then nothing. The source pipe has a T which goes to the manual foot pump and the
electric pump. The foot pump is pumping water but the
electric is behaving as described above. The
boat has 2 water
tanks and regardless which one is selected, the behavior is the same. I filled both tanks today and so it is not a matter of an empty tank. When I remove the source line from the
electric pump there is a trickle for a few seconds then nothing. The same for the foot pump source line. I can suck on the open hose and get a mouthful of water but it takes a fair amount of suction. I have spent the day today trying to figure out where the problem is. It appears that it is upstream of the pumps but there is no valve to open upstream to check for water. Are there any suggestions of what steps should be taken next?
