Hi, I am trying to run down a low water
pressure problem on my boat. We have a single
sink and shower
. There is a RV water
filter on the cold side of the sink. Barely any water will come out of the cold water at the sink. The hot water is not much better..I can put my thumb over the outlet and easily close off the hot water. The pump is an older Jabsco
36950-2000 I believe it is called a piston pump. The pump cycles as expected. There is an accumulator at the discharge of the pump. There is a tap at the discharge and I'm going to check pressure there. I am suspecting the pressure is just low coming out of the pump. I can't find much literature on the pump I have. Is the pressure regulation done integral to the pump? It is very hard to access the pump and I believe will require removal
of the hot water heater to get to it. I'd like to know for sure before I pull to rebuild
the pump. Would be nice if it was just an adjustment. Previous owner indicated they had great water pressure. I have verified nothing clogged in strainer of supply going to the pump. Thanks.
