Default Jabsco sticking

I have a Jabsco manual head and the pump handle sticks all the time. Once I get it going up and down a couple times it gets easy to pump. I really have yank it up pretty goodarn to get it started.

Do the make a lube for this you can pour in or do I remove the six screws on top and take the handle apart and use what to lube it?

It's sh÷ty job but somebody got to do it😠

Roger

That being said, I think I remember reading that petroleum jelly is the preferred lubricant. But, you need to get it on the seal faces, which means pulling the pump internals.

The head manual that was included in my 1990 2755SCR advises to fill the bowl about half full with warm water, then add a few drops of mineral oil (baby oil is mineral oil).

It advises to pump with long slow strokes until all the water is empty. Your pump handle should now work as new.

I do this once a year to mine and it is simply amazing the way it works.

Sorry - vaseline is petroleum based and not recommended for many types of rubber. Google it - Vaseline on rubber - and see what is said.

Forgot how good these u tube videos can be. I would of had the whole pump apart.

Undo the screw underneath the handle and assembly comes out . They say to use a silicone lub and grease the stem and put everything back ...you are done! Not bad..

I have purpose tomorrow after I do my walking��

Thanks Jesse and Jim for the info.

Roger☺

Roger, this is how it starts. Then eventually the rubber gasket starts to wear out. the next symptom is it wil dry flush ok, but not draw in raw water. They make an entire pump assembly replacement. Undo the discharge hose, then unscrew, three screws. Remove the pump, put the new pump handle on, tighten three screws and reattach the discharge hose.

My only word of advise......pump about 5+ gallons of FRESHWATER into the head before you start the project. You WILL get backflow from the discharge pipe. This will ensure it is just freshwater.

The entire project took me less than an hour, and that includes cleaning the head when I was done.

Boating on a muddy river like the Illinois river I have never use the river water to flush with. Instead I have had a milk jug of tap water for that use. I am wondering what caused this in the first place. Maybe just normal maintenance, I will find out this afternoon when I get down to the marina.

Well that was easy. Lifted the handle up, unscrewed the plastic nut holding the pump handlet assembly and out it came. Cleaned both shafts and assembly and then sprayed everything with a silicone spray. Boy what a difference! That handle glides up and down with ease now, sweet! Took me about 15 minutes to do all this.

Thanks guys for help!

I'm getting around 5 years between pump rebuilds. I think you're seeing a normal duty cycle. The rebuild kit is cheaper than the entire pump. Technically the shell, elbow, pump handle and rod don't need to be replaced. The cost for a entire assembly is the cost of simplifying the job in my mind.
