    Newty, I got out on the lake this sunday to do some surfing and one thing i found out, All the valves need to be the same size, i have one 1" and two 3/4" valve on it right now. What would happen is the 1" valve would open if i was using one of the smaller valves to fill a bag up. At this point i think im going to make a run the the home depot and get 2 more 1" valves.

    Do you think the thru hull can handle haveing 2 800gph pumps? works out to 26.6 gpm. I remember you wrote somthing about gpm flow thru 3/4 pipeing but i cant find that now.

    what is causing the 1" to open when other valves are open? I would think it wouldn't matter?

    I took the springs out of all the valves and im thinking that the 1" valve just has less resestance and is opening. This is a work in progress, not sure if i will be ever done.

    Maybe lighter springs can be had, rather than going springless?

    not a bad idea-might cut some spring's down a little and see what happens

    I think the flow at the pressure of the pump will not make much difference for the 3/4 or 1" valve. did you notice an increase flow in the 1" valve?

    i wish you guys would get this figured out so i can know what change to make and what will work. is there anything to that guys comment on wakeworld about unwanted flows, or what ever his concern was?

    3/4 should be good for up to 30gpm with a very short run. Like what I have. There is less resistance with the 1 inch, is all I can think of that would cause the 1 to leak by.
    My original thought on the valves when I first pulled them apart was to cut the spring down a little to see if it would work when I found the no spring thing.

    Most springs get stronger when shorter! If there is room, you could try two original springs. I was thinking of a single, weaker replacement though.

    thought about this in the am. keeping in mind that irrigation systems have 40-60psi at the entry end of the valve all the time, perhaps the spring is there to keep the system shut until the valve is energized and then it opens. in our system, the valve wouldn't open due to the low water pressure with the pump off, but as soon as you start filling, pressure is there, and no spring to keep it shut? since the valves in a typical irrigation system do not have power constantly, only when opened, something must be there to counteract the force of the water pressure at the entry.

    thoughts on that?
