    I am asking for some advice from the drillers and others with flush carts on this forum.
    Here is my problem:
    8 year old single pump (26-99) double-O Ring type pressurized flow center
    The composite 3-way valves have not been turned in those 8 years, and now
    seem to be stuck. I've tried to turn them with a 8" 3/8" drive breaker bar,
    but I was afraid to apply too much force and break something.

    Do I try to rock them back and forth, etc. or is it time for a new flow center?
    I'm going to await until spring in any case to try again.
    Am I just looking for trouble and should just leave it alone?

    Hi and welcome!
    From a service standpoint, the only time those valves need to operate is to perform service. Sooo if it is not needing service, let it be. A single pump flow center is going to set you back a big chunk of cash if you need to replace. It has been my experiance that forcing those valves to turn is a 50/50 proposition. Some times they break free and no issues, some times the o rings are damaged and you are screwed. The o rings are non serviceable.
    Hope this helps

    Thank you Eric!
    I will leave it alone.
    I will plan on going to non pressurized
    when it needs to be replaced.
