freshwater system problem

hi i am having some problems with the freshwater system aboard my 38 ocean. we first took out the pump and got an electrician to check it and it was fine, we then changed the presure tank and bled all the wtaerlines and we are still getting low water pressure. any ideas
thanks in advance

I would check two more things..check valves..they do go bad..

Does the pump cycle and shut off quickly bringing up the pressure on the tank?

If not, trace all the lines, pinhole, crack or kink.

Use process of elimation..start at the pressure side of the tank..and work towards the outlets..you'll find it.

What kind of pump it?
Does it have a gauge? if so what is the pressure.

thankss for the help canyon and yea the pump cycles to keep the pressure built up and well when the sink or shower is used the epump willl run continuosly, i will have to run throught the system again.

thanks fast yea its a shurflo 40 psi 12 volt pump set up with a pressure tank. i will have to monitor the gaugee on the pressure tank, if not im going to chek the voltage at the pump there mite be a wiring problem thanks again

If the pump cycles a lot you may have too much air in the expansion tank.
Low flow could be as simple as dirty screens at your fixtures OR a leak before the pump.
If you have a water filter before the pump check it for air leaks. A piece of clear tubing before the pump will let you see if there are any air bubbles, that would indicate a down stream leak.
This same thing drove me nuts on my 38'.

thanks man and yea we cleaned the filter before the pump and it was good . we also undid every hoes and water was flowing clean and smooth no sputtering. then after fighting up for the day we gave up and then tried the tap and it worked for a lil while with good pressure, maybe the boat has a ghost haha
thanks for the advice

What type water filter do you have?

I had the exact same problem on my 1989 44 Ocean. It first started out only doign that occasionally and then it became almost constant.

Found out that the original water filter cannister design just wasn't that great. Replaced the unit with a household unit from Home Depot...GE Smartwater. Have not had a problem in 18 months.

Good luck!

Long shot here ,? have you checked the overflow vent ,is it possabile to have vapor lock

I have had issues like this in the past and it led to the screen in the cockpit were the dock water enters........
