I have naturally warm, hard water and after several years (5 - 6 yrs) of use my sprinklers do not shut off. I've found replacing the valve diaphragm solves this shut off problem.
These new diaphragms seem to be better than the original ones that came with the valves that I put in back in 1998. I have not replaced any of these new diaphragms and some have been in use for 7 - 8 yrs.
This is good for exact model replacements. The replacement diaphragm looks like it will fit earlier models of the PGV valves but there is a subtle size difference that makes it hit and miss. It's been my experience that if the older model has failed you are better off replacing the entire valve.
Hope this helps.
USUALLY, THESE VALVES FAIL TO OPEN IF THE DIAPHRAGM IS BAD.
However, I did have the same problem a couple of weeks ago. When I took it apart, the white plastic cylinder that is part of the diaphrgm had some imbedded dirt which apparently kept the valve from closing. I cleaned the valve and replaced the diaphrgm (it looked ok but they only cost a few dollaers) and the valve works fine now.
is for all hunter PGV,ASV,SRV 1 inch valves. I don't know about the 3/4 inch
ASV and it has a Numbed for a diaphram . Suggest you check out other WEB site and come back here to buy.
where can I speak to someone to walk me through repairing my sprinkler heads?
2. Look at the diagram - Sprinkler Warehouse website.
3. Clean the area around the sprinkler. You do not want any dirt to fall into the open sprinkler. And be sure the water is OFF.
4. Depending on the type of valve you will need (mine are covered with 2' of snow so I'm not able to go look at the valve) a screwdriver to undo the 4 screws. Or a channel lock to unscrew the cover.
5. Carefully remove the valve diaphragm and inspect it. Looks for nicks and tears. We are on a well and get lots of small "rocks" and silt which causes some leaks.
6. If you are sure that you have opened the leaking valve . . . . replace the diaphragm.
Should take you about 20 minutes on the first valve and 10 minutes on all of the rest.
7. It is a good idea to clean (with a rag) all of the valve diaphragms every year.
for the Hunter 33-200 1" PGV valve is 56mm (2. 3/16")
The 1" refers to the nominal pipe size.
