    Retro Toro, late 70's early 80's Toro had the market. Rainbird sucked, never heard of Richdel.

    It's not the valves that are at fault, it's not the difference between using rectorseal or teflon tape: it's incorrect installation of the m.p.t.s, period.

    What, are you proud? Why use paste on small valves anyway?

    Why not? The correct application is the answer, I quit using tape years ago.

    I use the 1" DVF and the 3/4" and 1" A/S version of this valve (ASVF) all the time with either PVC MAs or a TOE or TBE nipple.

    I use 4 to 5 wraps of Teflon tape and that's all. Hand tight and maybe just a 1/4 turn with the wrench for good measure.

    Teflon paste makes it very easy to overtighten. Because the threads are slightly tapered, the farther they insert, the more pressure is exerted on the threaded portion of the body. I only use the paste on metal to metal connections.

    W*M valve parts have been interchangeable for years and years, as well.

    W*M sucks too. Solenoids and smartlines piss me off.

    I have been patient with rain bird thus far, but I am def looking into other valves. I have used weathermatic, easy to work on but gaskets are damaged easily and solenoids go out constantly, not good for our 3 year warranty...

    Well............ WELLL!!!

    Call it a hunch...

    But since the rain bird dvf is one of the top selling valves to residential professionals... And... you don't see too many other threads on this ( There are, however in comparison to other valves it's relative) Particularly there might be a slight more complaints because the % of use is generally much higher the other valves.

    Don't you think some other factors could play into effect here instead of just Blaming the Industry suppling companies?

    I'm just saying I live in wa too and haven't had this problem... Consider other avenues?

    In any case.. I do feel bad that you are dealing with this and having so many damn issues!

    I don't recommend to paste plastics and only paste /teflon metals.. that's my opinion.. I don't recommend more then 3-5 wraps... and on sched 40 Mipt's (male adapters) to leave at least 3 threads showing...

    Also.. Do you buy in large bulk? You could have just had a bad batch?
