Replace The “Top-Of-The-Valve” Using Parts From A New Valve Of The Same Make And Model
When you have a faulty solenoid, It is better to buy the valve and take the top off the new valve and replace the old valve top. Plus a new valve is cheaper than if you buy the parts separately. This way you will end up with a new diaphragm, solenoid, and internal filters. You will have a new valve since the bottom body piece is only a PVC base and does not go bad. The trick is you must use the exact model valve as the old valve. If you can not find the same valve (if yours is so old that we do not have it online) then we suggest you replace the entire valve.
