just a pre-emptive question regarding orbit watermaster

Got the RainBird JTV-100 Jar top valve, works perfectly (minus honking), problem solved. Thanks muchly.

To solve the honking just mod it modding is really easy so you shouldnt have a problem doing that.

I really really don't want to mod it though. Electric firing is sexy. The honking however, isn't. From what I can tell it's because the pilot valve that the solenoid opens is so small. I'll try to figure something out about it. But I'd really like to keep it electric. I've lubed it but that does nothing. any suggestions? Err, I yanked out the little white thing on the diaphragm like you said because it still took a second or two to close the valve... And now air just hisses out when I open it. ???

[Extrusion]

Try putting the white thing back it honks because the diaphram is vibrating only way to really solve it it to mod it and btw modding it makes it let air out 10 times faster not sure if 10times is the true number but spudtech's guide on modding says 10 times faster so youll get alot more power out of it and it like a trigger if you use a blow gun.

Yeah I decided i can't do the honking for much longer. Also yeah I put the white thing back in and it's back to working. I've got everything I need but some epoxy.

You could use a smaller (half-inch maybe?) sprinkler valve to pilot your 1" valve... That way you could trigger the pilot valve electrically, and have a pneumatically triggered main valve. It'd be a bit pricy, but you'd get the best of both worlds.

Peace,

They don't make 1/2" sprinkler valves but you could get a solonoid valve from www.mcmaster.com.

that sound cool.

[SpudStuff]

That was useless...

1. What sounds cool?
2. Spell Check.

The most cost effective solution for the venting would be using a high flow blowgun or a 1/4" ball valve. If all else fails you can use another 3/4" valve epoxied to the top.

What's the stamp on your Orbit Watermaster? The last few I got from Home Depot had poorly cleaned parts on the seal face. These were six digit 5xxxxx stamps. I've had valves from 3 different states (south, midwest) and they were the same. The trick was to open the valve and clean out the burrs with a boxcutter. I had a thread with pictures here somewhere.

The inner rim of that white portion shouldn't have that excess molded plastic. This one is pretty bad, so it was returned. Some of the ones I got from the midwest were better than from the south. They had just a few burrs which were easily scraped off with a box cutter. After that they sealed fine.

Lol read my last few posts. I exchanged it for a JTV-100 jar top waterbird. This thing is awesome. It's smaller profile, and there's no screws. It's gonna be uber easy to mod. (Once I get epoxy and a set of taps from a friend I'll do just that.)

[zerodivide]

Ah, problem solved then. You have any pics of the JTV-100?

[SpudStuff]

You don't need the taps, just drill a 1/2" hole and thread the nipple in. But if you have the taps use them.

Here is a tutorial on that valve.

Ah, then i'll just drill the hole and save myself alot of asking and waiting. Thanks for the help, we'll see how it goes after i get some epoxy.
