water pressure problems

Can't seem to figure out our water pressure system problem and unfamiliar with a sailboat water pressure system.

What the system is doing:
- Water spits and sputters at all water faucet locations and not holding pressure. Pump is getting hot so we shut it off.
We do see water entering the line into the pump, fresh water tank is full and the valve is on at the tank and there appears to be no other valve within the system.
Perhaps there is air in the lines? Not sure how to bleed the lines.

Re: water pressure problems

Is this a new boat to you?

Most owners will drain the HW tank and leave the valve open.

Re: water pressure problems

yes, purchase this past winter and was on the hard until a few months ago and have not used the pressure water system until this week.

Talk to the PO if possible. If not, you will need to trace all your lines to see if you are missing something. It is also possible that the air in your HW tank is not being bled. Try running only hte hot water faucet. It could take a while to bleed. Maybe 5-10 minutes. If the pump gets hot, shut it off and lett it cool and continue.

Check your bilges to see if the water level is increasing.

Re: water pressure problems

There should be a fresh water filter on the inlet side of the pump. That filter may be clogged.

Usually all that's necessary to bleed, is to turn off the pump, open all the faucets, and fill the tank to the brim. The top of the filler is the highest point in the system so will act as the priming point. Keep the hose running (doesn't matter if it's overflowing a bit over the deck) until water flows air-free from the taps. NB, if the bilge pump goes nuts at this point, that's telling you there's a leak. Go find it now, while it's leaking.

Re: water pressure problems

Patrick,

You might just have a small diaphragm pump. Some of these will mimic air in the line due to the on/off nature of the water flowing through them. It could also be that the pump is getting hot from the hot water flowing through it, not a pump problem.

Try running it with cold water, if it still overheats, you probably need a new pump.

Re: water pressure problems

check if you have an in line filter for the water...mine was plugged and letting very little water through...and I had similar symptoms as what you describe.

Re: water pressure problems

My guess: I encountered the same problem. The solution was simple: 1st, if you have both manual and electric pumps using the same line, you must have cut-off valves on the lines to the hand pumps. If not, the electric pump will suck air back through the valve(s) of the hand-pumps and into the electric pump, thus causing the electric pump to loose it prime and overheat. Once I closed the hand-pump shut-off valves, the electric pump put out all the pressure you could ask for.

Good Luck,

Gary
