    I guess anything is possible. You could remote mount it too.

    Keep in mind there is a lot of pressure at that point.

    I might not be Pete and I have never used that valve or anything like it. But IMHO common sense tells me it should work. I suspect you would get a lot of air in the lines if your filter gets blocked. But that is a lot easier to fix than replacing diaphragms.

    Okay, I'm starting to come to some conclusions here... just a few more questions...

    If I were to go with a D30, what spare parts should I have as backups? I only use the sprayer 1 day a week, spraying out about 300g each time. Sooo, 30 weeks x 300g = 9,000 annually. (Maybe a round 10,000 gallons per season would cover incidentals...)

    Here's the exploded view of the pump:

    And here's the repair kit that rittenhouse sells (though I don't see the infamous red biscuit in there):

    Thanks.

    Okay, this is the regulator connection. Is it the same for the D30? I couldn't verify it through pictures...

    And another idiot question: how do I get the pump off the gear box? I removed the 4 allen heads that bolt it to the pump... but it's still connected somehow. What do I do to separate the two?

    whoop

    The only parts i ever keep are the diaphrams, #5-2-of them, 1- #46 and 1 #61.

    #61 is the one I have had to change the most, I think because it dry rots from the outside. It still will last longer than a year.

    On my old pump that I ran for years, I never changed the valves, could never see wear on them. I would change the o-rings just because they came with the kit.

    The problem with the D30 reg is it sits a little lower, and that pump head right below the flange will get in the way of the reg.

    To get the gearbox off, split the gearbox in the middle, to give yourself a little room to work. Then you will see a big gear inside the gearbox that is attached to the pump. That is why the pump is not coming off the gearbox right now.

    Almost forgot. Underneath the gearbox there is another small bolt that goes in the opposite direction of the 4 bolts you circled.

    Look for a bolt in the bottom also.
