Work for me perfectly after installed.
The video from your company helped me order the right part as no sprinkler manual was left at my house when I bought it. The part worked great and my system was up and running after installed. The only downfall was the cost of shipping the product cost more than the part I needed.

Diaphram is Direct Replacement
The diaphragms came packaged well, fresh rubber, pliable and fit perfectly. The old diaphragm had a micro pin hole that caused the valve to open. These replacements took care of the problem.

great service and had the parts
zone water would not shut-off completely and replacing the diaphragm fixed it.

This diaphragm is an easy fix for valves that won't shut off. Don't replace the valve! Keep these on hand and you can change it out in less than 15 minutes.

The diaphragm was a perfect fit, and the next day shipping service was just in time - thanks for all!
The Weathermatic replacement diaphragm was exactly what was needed for my sprinkler system - a perfect fit! Thanks for the pics and troubleshooting guide- helped me narrow down to match my system.

don't fit
Parts are for a one inch valve but do not fit my valve body. My one inch valve is larger in diameter. Can't wait for replacement so I am moving to Orbit valves.

Again, so as not to have to replace the entire valve!!! Much more cost effective for the customer and a great time saver for us.

How do I know which valve I have. I need diaphragm for valve?
A shopper on Oct 22, 2015
BEST ANSWER: It's not easy. Look at the pictures of valves on the website. Look for similar shapes, number of screws, shape and position of the solenoid. If you find one that looks close, go to that manufacturers website and look at the same features (shape, screws, solenoid). If you find one that looks right you can make and educated guess and buy the diaphragm for that valve or go one step further and remove the diaphragm from your valve and compare that with the picture of the diaphragm you think you need. No guarantees this diaphragm will be right, just your best educated guess.
Weathermatic Nitro-100 valve closing slowly and makes noise. What is the problem?
A shopper on Aug 15, 2016
BEST ANSWER: In my experience it is usually the diaphragm, you might as well buy several because sooner or later you have to replace all of them, or replace all the valves with s-2400 irritrol valves their better.
