Head pump sticks

I have a manual pump head that I installed about 2 seasons ago. The pump on it is starting to stick a lot. Especially now that she just went back in the water after sitting all winter. Can I use lock carbon on it or WD40? Is there a special lube for it.

Re: Head pump sticks

A few years ago, my manual pump was squealing a lot. I poured a couple ounces of cooking oil in the head. Squeal went away and pump worked much better. Seems I got the idea from Peggy Hall.

Re: Head pump sticks

What pump do you have?

If it’s the ubiquitous Jabsco, there is a large nut that forms the seal holder in top of the pump. Using an adjustable spanner (wrench in USA ) pull the pump handle to the top, undo the nut, tip the shaft to the side to vent the pump (stops water spilling into the boat) and remove the plunger. A small amount of waterproof grease on your finger, wipe it onto the inside of the pump cylinder and reassemble.

Takes five minutes, will stop the sticking for a few months. There will be some who say “oh yes, but the grease will damage the seal”. Yes it will over several years. When it does, a dollar will buy a new o-ring that will last the next five years. Insert it next time you fix the sticky. 😊

Re: Head pump sticks

Don't bother with cooking oil, etc - they last a week or two at best, and are not the correct solution.

Do what Cassidy recommended, only use SuperLube as the grease. This is what the toilet is manufactured and shipped with, and it will not harm the seals.

A dose of SuperLube and it won't squeak for 6-12 months.
