Title: Port side water tank
Post by: sfomarc on November 20, 2020, 07:16:26 PM

I am new to my 32 Pearson and sailing.  I drained the SB water tank using the galley sink under pressure. The Port side tank will not drain.  Any suggestions?  I was thinking that there is a shutoff valve that I am missing but can't seem to find it.  Thanks

my 31-2 has 2 water shut off valves under the sink. It allows you to choose which tank to use and be aware of your usage. There must be something similar somewhere on yours.

My 323 also has the shutoff valves under the sink.

Yes.  Mine does as well.  SB and port lines run into a tee, with a shutoff valve for each side.  I swapped the supply lines so that the port feed came into the SB side of the tee through and associated shutoff valve, thinking that maybe the port side valve under the sink failed but no luck.  I see the pump is pulling water within a couple inches of the shutoff valve, but doesn't budge beyond that.

I am replacing all water lines, valves and probably the pump since it is the original one with a belt.  Figure I replace it before it fails while everything is pulled apart.

Thanks for the input

sounds to me like you only need to change the pump as it appears there's not enough suction to draw from the Starboard tank. There could also be some blockage affecting it, which changing all your lines should rectify as well, but maybe change the pump first and go from there :)

Agree on replacing the pump.  It is pretty loud and appears to be the original pump with a pulley.  Replacing water lines for peace of mind knowing that the lines are clean and new.

Thank you.

I use the galley sink foot pump to prime when the electric pump has trouble drawing water up to the valves under the sink.

Another possibility is that you have an air leak on the side that won't pump.

Hang on to that OEM pump.  Rebuild kits are still available, and its a very rugged design.  I looked it up, and replacements are are over $400!! Jabsco pumps are cheap, but you'll be replacing them every few years.  My OEM pump has lasted over 40 years with only one rebuild!
