Great service from Weathermatic technical support person. He took his time listened to me and got me the numbers that I needed to have for ordering the correct valve.
We have had Weathermatic valves on our sprinkler system since 1978 or 1979. We have replaced only one valve and I am sure it would not have had to be replaced if I could have found the replacement diaphragms, but I was told that they no longer existed. Since I found that they were replaceable, I have replaced 4 diaphragms and I purchased 5 more for back-ups. I was told that valves lasted only 5-8 years. Ours are 40 years old and after replacing the diaphragms they are working like new, and maybe better than ever.

We were informed parts were on back order and due in stock in a few days. The stock arrived as stated and our order was fulfilled immediately. Excellent service.

Diaphragm Assembly
Received the part promptly, and replaced it in the valve. Works great now. Watched some you tube videos for helpful hints.

Repair broken valves (diaphragm gets tears in them); more cost effective than replacing whole valve.

I have to keep replacing them because they keep malfunctioning, because of the heat, I guess.

Does this come with the brass plate and brass shock cone?
David C on Apr 10, 2018
BEST ANSWER: Sorry, I've been out of town. I just checked and what you get is just the rubber diaphragm, no brass anywhere on it or with it.
what is the diameter of the diaphragm?
A shopper on Nov 2, 2018
BEST ANSWER: Questing around 2 1/4 Inches in diameter
Does this diaphragm replace diaphragm for old brass weathermatic ?and was there a three-quarter inch ever made of the brass weathermatic?
