check valves

[Steve in Omaha]

Any maintenance needed? How often should they be replaced?


Thanks

I just found the check ball in one of my jets :mrgreen:

Steve;

We have seen them stick from time to time.

Probably from chemical residue (customers not using our chemicals).

I would clean them in a mild acid solution.

On the wand.

Mine are about a year old and are starting to leak.

Take the jet off and inside the check valve is a hex screw ...I take mine completely out and flush it with water in case I have something stuck under the little ball or the spring........

Put it all back together and snug down the hex screw and then back it off about a 1/4 to a 1/2 turn...

Just don't do what I did and when you put the jets back on..... don't tighten them to much to the check valve will crack and you will be calling Greenie.............

We seem to get two good years from a set of checkvalve jet extenders, probably could get much much more but the occasional scratched brass body or chem residue makes most guys just put in a new set and be done with the guessing.

Everyone above is correct, it's just a ball, a tapered spring , and brass Allen head "keeper" that holds them in, I will emphasize they are made of brass and on purpose, with a nickle plate, it's the brass between two stainless parts, the jet and the jet manifold, so you will never strip a thread at a bad time. As a final note, the SS jets do seem to do BETTER with a double wrap of teflon tape so you don't tend to bottom the jet out in the checkvalve, you SHOULD still see threads on the SS jet when it's snug.

Thanks to all.

Took them apart last night as soaked them in vinegar then reassembled. Worked like a charm today, no leaks!
