Anti-siphon repair kit.
New anti-siphon (brass) cost $32. The repair kit cost $4. Rebuilt the old vavle with this kit and it is working like it was brand new. 28 reasons why to buy the repair kit!!! Would recommend this product.

Perfect fit
It's an exact replacement for the Champion RK 30C. These are Sprinkler Warehouse parts without the Champion price.

Will this kit also work with orbit valve #51016?

BEST ANSWER: No idea if it will work for an Orbit.

I bought the kit to fix an old Rain Bird manual brass anti-siphon valve (per a comment on the internet). None of the parts in the RK1 fit my valve so I had to fix it another way.
Does anyone know if there is any information on how to install this kit? thanks

BEST ANSWER: It's been awhile since I had one apart, but I can give a couple of tips from notes. Of course you have to remove the big piece with the cross-handle on top. Use a crescent wrench or a 7/8'' wrench below the diaphragm housing. It may be corroded in place so you may have to strike the wrench. You probably don't need to remove the 8 little screws to expose the diaphragm, because it is almost never the problem.

That exposes 2 of your parts, the thick rubber washer and one of the gaskets. The thick washer is usually one of the problems--it can wear a deep groove in the surface. You can turn it over and use it again.

You can remove the top of the anti-siphon valve by hand, more likely a wrench, exposing two more parts, the plastic and rubber valve, and another of the large gaskets. I don't know where the final part which looks like a 1/4 inch length of 1/2 inch hose. maybe it's for another model.


If you try to remove the little bronze bleed valve, work it back and forth carefully or the threads may strip.

If you remove the center post of the solenoid, don't screw it down too hard or your valve won't open. Coat the o-ring with a tiny bit of silicone grease so you can seat it with minimal pressure.

If the main valve seat is corroded it may leak. You'll have to get clever to grind it down a little bit by hand, Or try to find a cheap valve-seat resurfacer.

Good Luck
I need to rebuild an old Champion valve. The Numbers on the side are A6?66 . It could be a 46 66 I am not sure. There are 4 bolts holding the Bonet on. What rebuild kit should I buy?
