Water Preasure

I have a 1987 Cal 33-2 and am experiencing what appears to be an air leak in the preasure water system. The pump had been re cycling for just a second or two every 10 minutes or so and I was not able to locate the probable leak. We had installed a new water heater and so checked this carefully and there are no leaks there. We just learned to live with the re cycling or kept the preasure of unless we were using water. A new problem has developed. When turning the preasure switch on after it has been off for an hour or so there is a lot of air in the system that has to be blead off at the faucet (about a minute or so) before water is being pumped. I'm not sure as to where to start looking; a broken pump, somewhere along the line from the tank to the fuucet or where ever. Any ideas? Jim O'C Ariel

If you are having to vent air and it is difficult to getting the pump to prime, there must be a leak somewhere between the water source and the inlet of the pump. Or possibly in the pump itself, such as a leaking shaft seal or or even a crack in the pump head. You might check, also, any strainers in the suctions side of the system.

Bleed the system....mine will cycle until I get all the air out...I have a bleed value before the pump in my water filter canister. Also, check all the hose clamps. Good Luck!

Jim, I agree with Walter and Greg, to build up air in a pump or pressure line, without evidence of a leak, you are sucking air from the vacuum side of the pump. Is this the original pump? We had to replace ours about two years ago. We ended up with a new higher volume flowJet from a RV dealer in town. I relocated the pump to a board across the stringers under the sink. I isolated the board with a cushion of cured silicone. With the rubber isolation pads on the new pump, this is now super quiet! Our three way valve (tank valve) did not appear to be original. I think a PO switched the tank valve out to a less expensive valve for some reason. Since the valve was getting difficult to turn, I replaced this as well. The only valve I could find was one used to "winterize" water systems. This works well for our application. The old filter (incoming line after the valve) also started leaking (could be a source of your leak). Again, the RV store has the exact same in line filter. I don't think I saved a lot of money (except for the pump) buying from a RV dealer. The Dealer is open during the week while I am at home, and I don't have to depend on the local (to the boat) WM or chandlery to order what they have in a catalog.

Is there any difference in how serious this problem is depending on how recently the tanks were filled? I had a similar problem that seemed intermittent and after checking (and replacing) hoses, clamps, etc. multiple times, I finally figured out that the problem was with the old copper tank taps - over time from corrosion they had developed numerous pinholes and as the water level in the tanks declined more and more air could get into the lines. It wasn't constant though because with the rolling of the boat sometimes the tap would be totally submerged when the pump was operating even if the tank was really only half full. Took me two years to figure this one out. Once the taps were replaced the problem was gone.

I had to take out the in-line filter to stop a similar leak in the pressure water system. MIke Kennedy Conquest Cal 40 # 96
