Is the measurement across only the center or the entire piece? I measured completely across and it's 2 1/8?
A shopper on Mar 8, 2017
do you need a special tool to twist off the jar top valve? Sorry!
A shopper on Jan 26, 2012
BEST ANSWER: No. You simply un-screw the valve cover (most likely with a phillips screwdriver). After you take off the valve cover, you will see this diaphragm (it is upside down from the picture shown). You can simply reach in with your hand and pull the old valve off with your finger. Make sure you have shut off the water to your line or your master valve to your sprinkler system is off. Even then, you may have a small amount of water come out of the valve (should be just what is already in the line) when you remove the diaphragm.

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.
Will the Hunter 33-2100 replacement diaphragm work in the SRV valves?
D. Blake on Aug 27, 2013
BEST ANSWER: Replacing teh 33-2100 diaphragm is very simple - just pop the valve top, remove the old diaphragm - note where the tab aligns - and clean the valve body before installing the new on.

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.
is this the part that needs replacing once a valve starts leaking? do i need an O-ring also?
A shopper on Mar 18, 2013
BEST ANSWER: By leaking valves, do you mean the valve body leaking or water bleeding through the valve after shut off? If we're talking bleed through, I've generally found this to be the culprit/cause. If your valve is leaking at the body, it could be the body is cracked or a screw could be stripped and allowing water to flow. I have not any problems stemming from the o-rings.
I am replacing this diaphragm, When purchased, there is no spring included. Where do I find a replacement spring. ? Did not see one in the valve when I removed the cover. Thanks.
J.P. k on Jul 28, 2012
BEST ANSWER: We don't offer the spring separately.
Can you buy the white plastic strainer that the diaphragm sits in?
Mike on Jul 18, 2016
BEST ANSWER: As far as I know, the strainer is only available when you purchase a new valve body.
One of my valves seems to be allowing a trickle of water even when the solenoid is off. Is this some thing that can be corrected by replacing the valve diaphragm?
Bill K on Jun 3, 2015
BEST ANSWER: I had the same issue with a couple of my valves and replaced with the diaphragm and it fixed my problem. Hence I ordered more and replaced the remaining ones as well.
My sprinklers stay on even though the controller has shutoff the valve. If I manually close the valve through the solenoid then the sprinklers shutoff. Do you think it is the diaphragm?
jerry t on Jun 3, 2013
BEST ANSWER: I am assuming that the solenoid body is screwed tight clockwise and still not sutting off. I'm not sure what you mean about manually closing the valve.
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.
I am running a Hunter system with 6 of these valves. Water is sourced from a borehole, is crystal clear but if anything, is possibly high in calcium content. I'm having to replace the diaphragms about every 16 months when I have to pressurize/prime the system from an external source to get it going. Once running, the valves change over ok. Why would the diaphragms deteriorate so quickly?
A shopper on Mar 21, 2012
BEST ANSWER: NOT SURE WHAT IS THE MAIN SOURSE IS , BUT MUST BE A GROUND WELL SET UP SYSTEM. IF HIGH IN CALCIUM OR IRON, COULD BE THAT WHEN HE ATTEMPTS TO PRIME OR PUT PRESSURE IN SYSTEM , SOME OF THE CALCIUM BUILD UP BREAKS LOSE AND GETS INTO THE VALVE DIAPHRAGM HOLD OR IN THE LITTLE BULB THAT FITS IN THE MAIN VALVE. ALSO HE NEEDS TO CHECK THE WHITE COATING ON THE CENTER PIECE OF THE DIAPHRAGM . I HAVE FOUND A FEW THAT THE WHITE SUBSTANCE FLAKES OFF AND GETS IN THE LITTLE HOLDS OF RUBBER DIAPHRAGM. DON'T KNOW WHAT IS MEANT BY "VALVES CHANGE OVER WHEN SYSTEM RESTARTES. ALSO TO WHAT DEGREE IS DETERIOATION OF THE DIAPHRAGM,SOFT RUBBER,OR JUST STOPED UP.? CAN GET A STRAIGHT PIN AND CLEAN THOSE HOLES THAT HAVE CLOSED OR DECREASED IN SIZE. THEN WASH OUT OR MAY TRY A CALCIUM REMOVER. END. .
The valve I have ia a 3/4 inch with the model # ASV-075. Will the diaphram # 33-2100 fit this valve ?
A shopper on Sep 5, 2011
BEST ANSWER: I only have 1 inch valves . And this web site say that the diaphram #33-2100
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.
We want to replace the Diaphrams springs that's in the cover?
A shopper on Jun 8, 2018
BEST ANSWER: replacing these on 2 valves have corrected leaking that was occurring at the low-point head in 2 zones in my system. these work well
Does the 331300 ring come with the 332100 Hunter valve diaphragm?
Popsderf on Jul 26, 2017
BEST ANSWER: If you are talking about the ring you see in the picture then yes it does come with it.
how long will it take to get this part?
Brian C on Jun 2, 2015
BEST ANSWER: I got mine in less than a week. You should too if it's in stock. I would also order 1 or 2 more so you have a spare for later
is the separate white ring that goes underneath the diaphragm included?
Chris S on Nov 2, 2012
BEST ANSWER: What is pictured is all that is included. The white ring around the diaphragm is included. If you need the white plastic piece under the diaphragm (the piece that has a lot of holes in it) I think you will have to order a whole valve.
Does this part work on the Hunter PVG-075-ASV?
A shopper on Oct 4, 2017
BEST ANSWER: I would say that it should fit the hunter 3/4 asv valve.
will this diaphragm work in SRC unit ?
A shopper on Jul 9, 2017
BEST ANSWER: Sorry, not sure on the SRC valve body. I bought them for SRV valve bodies. They may be interchangeable, check online.
where is the closest Hunter parts distributor?
where can I speak to someone to walk me through repairing my sprinkler heads?
Ron R on Mar 23, 2016
BEST ANSWER: I. Get the model number of your sprinkler
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.
what is the outside diameter?
Paul D on Apr 6, 2015
BEST ANSWER: The outside diameter of the replacement diaphragm
for the Hunter 33-200 1" PGV valve is 56mm (2. 3/16")
The 1" refers to the nominal pipe size.
i visibly see a spray of water coming out of the top of the valve assembly. is this an indication of a broken top? or a failed diaphragm?
kevin g on Sep 13, 2014
BEST ANSWER: it soundslike a broken top or a loose solenoid
I have (8) Hunter 1" PGV valve with a jar top, & I need new diaphrams for all valves, (4 of 8 have seepage either at the valve itself or at the heads when system is off) I want to replace all of the diaphrams to ensure no seepage problems in future.My question is: Is there a difference between replacement diaphrams for valves with or without flow control?
A shopper on Jul 21, 2012
BEST ANSWER: Get the part number(s) and order new diaphragms. It's an easy fix.
I have a part number HCM 23100 9J STV the grey strip is burnt. Where can I get a replacement?
A shopper on Mar 3, 2016
BEST ANSWER: Where does this part go, into what(valve,controller,etc)? Who is the manufacturer? I'm not familiar with that part number.
Hunter zone not coming on unless top cover screws on valve are loosened. What is likely ti be the cause. Is there a way to check the diaphragm?
paul l on May 4, 2015
BEST ANSWER: Need to take out valve cover and inspect. Also look for debris in valve.
How do I know which diaphragm I need?
A shopper on Aug 10, 2012
BEST ANSWER: This is for the Jar top. Look at your valve and then match it to the pictures on this website
3/4 in valve ?
A shopper on Feb 12, 2012
BEST ANSWER: Not sure what the question is! ..to simply say "3/4 inch valve" is not a question.
I'm looking to replace a valve Diaphragm. I have a Hunter SRV valve. I noticed that while the 33-2100 part looks just like what I need, I also noticed there is a white ring with ridges and tiny holes that goes around the Valve Diaphragm. Does that need to be replaced along with the spring that is under the Valve Diaphragm?
Fernando C on Nov 21, 2011
BEST ANSWER: Unless the white ring and spring is damaged (which is not likely), you should be able to just replace eh diaphragm. I've replaced several diaphragms over the years, but never had to replace a ring or spring.
is the replacement diaphragm the same for the PGC-075-ASV and the 1 inch version?
A shopper on Jun 10, 2018
I have a hunter diaphragm that appears totally different than the ones shown. My irrigation system was installed ten years ago and might be a bit dated. The diaphragm has a cross on the middle with a small hole. Any idea where I can find it?
