Yes- The Old Leaking Head Problem

I have a Raritan manual pump head on board. The Flapper Valve leaks.

Raritan has told me that - since it is a rubber valve - I only need to "properly" tension the four housing screws that hold the valve in place between the base (below) and the pump housing (above).

Nigel Calder, in the Boat Owners Mechanical and Electrical Manual, suggests applying a little silicone between the leaves of the flapper valve to help the seal.

I have replaced the valve twice, fiddled endlessly with finding the "proper" screw tension, and applied silicone as NC suggests - the darn thing still leaks!!

This is a very common head - so I would think this is a very common problem. Has anyone out who has experienced this successfully resolved this?

Thanks in advance for your help.

Yes- The Old Leaking Head Problem

I am not sure how the problem was finally resolved, but I sailing ship I worked for had this problem a few times. One thing that seemed to help the frequency of the problem was to flush food grease from the stove to lube the valve regularly. It helped the problem but we had several occations of rebuilding the head.

Indeed I noticed the FAQs on this site recommend a cup of veg oil down the head from time to time. ... which seems to suggest, alternatively, you should eat more greasy food yourself ...sounds like a good excuse?!

Yes- The Old Leaking Head Problem

I am not sure if this will help your problem, it solved mine(after 1 1/2 years) of a leak from the joker valve and the flapper valve. I would have a build up of air after I used the pump. Eventually everything backed up and leaked. After using the head a couple of times it would leak when pumping. Quite by accident I was frustrated and took out the little nut type valve on the pump housing. Walla my leaks stopped. Put back in leaks were back. This little thing is called the Air Valve assembly part number 1203W has a little joker valve in it to release the pressure.
Anyway when I replaced it at the end of last season my leaks were gone.
As a note I had also called Rartitan and they were not much help.

Good Luck

John -

Interesting about the Air Valve. I recently replaced mine since the square housing broke (the valves still leaked before and after). If I remember correctly, when I removed the Airvalve and pumped, I got a jet of water shooting out of the hole where the Air Valve was. You didn''t have the same thing happen to you?
