These diaphragms solve no-open issues
If you have a situation where the zone won;t open and your diaphragms haven't been replaced for 10 years or longer they need to be changed out. Fairly easy job. These, I believe, are OEM and fit perfectly.

Our sprinkler system was installed in the early 90's and I could not find a replacement valve at any of the local hardware stores. One of our sprinkler zones stopped working due to a worn valve. This product worked perfectly and now the sprinkler zone is back up and running. Thanks for making this product available. We replaced it ourselves with the help of a YouTube video and it saved us the time and expense of calling in a professional. We have four sprinkler zones so we bought four in case any of the others need a replacement in the future. ??

Perfect replacement diaphragm for my super old Toro system. Saved me time and headache.
I have the Toro system that was designed poorly from many years ago. Didn’t want to dig it up again if I could avoid it. Searched all over and found these diaphragms for the extinct system. They work great!!!!! Fit perfect. Didn’t have to dig up the Toro dinosaur again. I’m so appreciative

So as not to have to replace the entire valve!!! Much more cost effective for the customer and a great time saver for us.<br /><br />Our area seems to have a lot of grit in the water, and even with filters, sometimes grit gets stuck in the diaphragm. Once the edge has been creased, it doesn't seem to go back to the correct shape. Also, many of our systems are older and we get lots of rust particles!

I need to clean or replace the diaphragm for the Toro Flo-Pro control valve. What is the proper method of replacement as I am having trouble replacing the diaphragm and getting the whole valve assembly back together?
A shopper on Apr 8, 2012
BEST ANSWER: My system is 20 years old and I have probably replaced all of them by now. It is fairly straightforward. It may be possible to leave the solenoid screwed into the cap, and that may be better because the older ones broke at the threads. You have to undo the cap which is about 4 inches or so in diameter. It has lugs on the top, and I made a special tool from a large piece of plastic threaded pipe connector (perhaps 3 inches diameter? Unsure of dimensions). Cut slots in one end to match the lugs on the cap. Slots in the other to take a wide flat piece of wood. The cap can then be unscrewed using a piece of wood, with a handle if necessary. This gives access to the gasket. You just take the old one out, and fit the new one over the long prong that is attached to the cap, and screw it back on.
Does this diaphram that the place of part number 89-2031?
A shopper on Sep 11, 2011
BEST ANSWER: I'm not sure if this diaphram is a replacement for the 89-2031. You might be able to find a good answer at the Toro Website?
does this include the spring that goes inside?
A shopper on Jun 2, 2012
BEST ANSWER: I put the diaphragm in tapered side down inside the valve. I tried it with the plastic ring up against the plastic tip of the metal shaft against it. That way still ran when the other zone is on. I turned the spring around with the plastic side down against the diaphragm and it still came on with the other zone. This is my second new valve. Should I try a third?
Is this diaphram better than the OEM type with the white tabs? Looking for one that might last longer.
Bill N on Jun 11, 2012
BEST ANSWER: I have had my system for 13yrs, and this is the first one that didn't work as well as it should. So I bought a few of these, for spares, and I installed one, and it is working fine. What ever you do don't cut off the little red plastic thing on the diaphram, even though it doesn't look like it belongs. I guess it's for removing and keeping sand and debri away from the small hole opening.
Hope this answers your question.

My system has five zones and functioned perfectly last season but now the no one zone pressures up but gradually slows down. There is plenty of pressure at the pump but the other zones do not come on. Question: I have replaced several diaphram assemblys in the past so would you suggest replacing all five ?
Bud O on May 21, 2011
I am a home owner and my irrigation system has become my hobby. I am not a pro.

Last year I replaced this same diaphram in 2 of my old toro valves. I did this because the valves were not holding back the pressure, leaking water through and would not shut off. This replacement solved my leaking problem.

This spring, one of these zones had low pressure. Only 1 of the 4 rotors on this zone popped up. I simply turned the valve open more to allow more flow. Make sure that you turned your valves all the way up to maximize flow when they are turned on. If you have constant water pressure, you should be good to go.

Another thing you might try is to turn off yoru water supply, remove your valve leaving the body open, turn the main water supply on, and let water pour out of your valve body for about a 1/2 minute. Then re-install the valve and see what happens. If this works on 1, do it on 2 through 5.

If none of this works, you might have a supply problem, AKA your pump is loosing pressure from a leaky seal, bad impeller, or lack of suficent water supply.

Again, I am not a pro, but this is just my thoughts.

I replaced this diaphragm because the zone would not come on. Now it is on all the time. I'm not sure how to replace the spring and the insides of the valve to get it to stop running when any of the other zones are on. I don't think I am putting it together right?
Bill H on Jun 18, 2012
I have my system divided into five zones. Three years ago one quit working and I replaced a diaphragm then another, in 2011 I replaced one more. For reasons I am not sure about they seem touchy to put together. Being sure there is not a speck of dirt where the diaphragm seats is essential. Any you are right getting things back together in the right order and right side up is essential. Each time I had one that did not work after I replaced the diaphragm I ended up taking apart one that WORKED and paying very close attention to what everything looked like and where they were. All work now and I have a bunch of extra diaphragms just in case. Eventually the diaphragm material looses its elasticity or deteriorates in some other way and it will have to be replaced. Once when I had a second zone that ran at the same time as the repaired zone it was because I had the controller set wrong.
I had broken a solenoid on my toro flo pro system (station #6)and replaced it with one from your site, then I had the same station (#6) not want to turn on but all the other stations worked fine. So I removed the diaphram from the station that had the new solenoid and wouldn't turn on and replaced the diaphram from a station that was not in use (#4). Now the station not in use (#4)is on at the same time as the station with the replaced solenoid (#6). Do I just need to replace the diaphram on the not used station too (#4)??
Nick W on Jul 11, 2011
BEST ANSWER: Nick - The short answer is YES. I have been down this road already. Since the diaphragm controls the water flow, whenever any other station comes on you will get flow through a station wiht no diaphragm (in this case, station 4). If station 4 is really not used at all, just take the non-functioning diaphragm (old one) and place it in station 4 - set your timer to 'off' or near zero (1 minute) and that zone will be skipped (or time-out) and no water will come out (cheap fix). If you want station 4 to work at some point, you'll need to put a new diaphragm in it.
I have a older toro sprinkler system. I am not sure if the valves are flo-pro or not. I believe the system is from roughly 1993. The valve cover has some numbers on it but does not mention flo-pro just toro and stamped area has 284 15 04 and it also has what appears to be B98. Is there a way to check to see what type of valves I have?
david w on Jun 21, 2014
BEST ANSWER: Here is how I would do it. If it is in directly in dirt like mine, dig up enough dirt so you can see what the valve looks like. Then go to Sprinkler Warehouse and click on lawn irrigation, then repair parts, then valve repair parts, then Toro parts. At that page click on a diaphragm, it will take you to another page and scroll down and you will see a blow up diagram of the valve. You can see if it is yours. If not, back up and try anther part. Also if you know the water line line size to the valve that may help narrow it down. You could take the screws out and take the top off and see what the insides look like. I have found that the things that fail are the diaphragm and solenoid. Good luck.

I have a jar top valve with part number 53804 for diaphragm. Do you have the diaphragm for the jar top valve?
Charles N on Oct 9, 2011
BEST ANSWER: Yes, I ordered it from Sprinkler Warehouse. Toro has stopped making that particular valve. But Sprinkler Warehouse has them. I have installed thousands of them. I wished Toro still made the whole valve. When the diaphragm needs replacing; it is hard to find any thing visible wrong. But usually a new diaphragm takes care of it for many more years.
does this replace the 290 06 04 diaphragm?
mike e on May 26, 2013
BEST ANSWER: I used this diaphragm in my 290 06 04 Toro Flo-Pro valve and it worked fine.
I replaced a leaky diaphragm and now the valve leaks and that valve won't turn on. The spring inside the unit has a plastic ring. does that ring go toward the top or the bottom of the valve? what are the little red clips on the side for? Does the diaphragm need to sit in the valve in any specific way? I had trouble putting it all back together. Finally I put the diaphragm in the valve put the spring over the hole, screwed on the lid, slid the metal shaft in the hole of the diaphragm and then screwed on the solenoid. Wat's the best procedure for putting it back together?
Bill S on May 28, 2012
BEST ANSWER: The Diaphragm sets down into the base. The tapered part of the diaphragm down inside the base. The spring with the plastic ring is posistioned UP against the cap. So the plastic ring goes towards the top. If you are careful you can place the spring with the ring and metal shaft into the cover that your will screw onto the base, it should stick there if you are slow and careful when you turn the cap over to screw onto the base. Turn the cap over and place it down on to the center of the diaphragm. You want to be sure that metal shaft is centered in the spring and centered into the bottom of the diaphragm. Then slowly screw on the cap. Reconnect the solenoid wires. Should be good to go.

Not sure what the red clip is for. Don't seem to serve any purpose as far as I could see. May have been a way for the manufacturer to ID this paticular diaphragm from another..
My system (Toro Pro Flo, 9 stations, about 45 sprinkler heads) is about 16 years old, so I'm prepared for some repair work on it. Nearly all the sprinkler heads seep a little water when they're not on, so I'm guessing the diaphragms are worn. I removed the diaphragm from one of the values, thus leaving it open, but even then there's barely enough pressure to raise even one of the heads on that station out of the ground. Could this be because the seeping at the other heads is reducing the pressure in the open station? I'm sure the pump is OK.

Also, when the solenoid clicks on, should there be any movement of parts inside the valve unit? Specifically, is the rod supposed to move freely?

Ken M on Jul 15, 2011
BEST ANSWER: I have city water (no pump). Even though you feel your pump is okay, I would install a pressure gage and open a valve on the pump outlet to see what happens to the pressure. Flow is probably more important than pressure.
When the solenoid clicks on to open the valve, the stainless rod does not move. The solenoid plunger moves to open the top of the rod to depressure the space above the diaphram, and the inlet water pressure below the diaghram opens the value (pushing the diaphram up) to allow the water to flow to that zone. When the solenoid closes to shut off the water, the spring above the diaphram pushes it closed and the small vent in the diaphram allows the pressure to equalize on both sides of the diaphram.
My system is 14 years old (has 7 zones) and I have replaced 4 diaphrams and 3 solenoids.
I'm still looking for a response to my question from sprinkler warehouse or from someone else that may have information about the Toro 3/4" electric sprinkler valve model 53285 and it's replacement diaphagm model 53349. If this is the normal response time (more than several weeks) it takes to get a replacement response, I guess Toro or any related vendors that handle Toro products is not a company that should be used?
melvin q on Jun 29, 2012
BEST ANSWER: My order was filled quickly and replacement part fixed my valve.
I have a 20 year old system with Toro jarhead values. I believe the diaphram part number is 35-3503. Will this diaphram work?
Ann M on Jun 18, 2012

Not entirely sure if that would work. I'd buy one and try it out. I have 7 Flo Pro valves and was having trouble with them. Replaced the diaphragms and the solenoids and theyre like new. There is some technique involves in getting the spindle seated correctly. Patience and practice and you'll get it to work.
Can this diaphragm replace Toro diaphragm 89-0993? What is the difference between the two? The difference I can tell is the different color of center plastic. Black->89-9861, white->89-0993. Thanks.
Yiping Z on Jun 12, 2012
BEST ANSWER: yes ......either one will work.
I just ordered two of these and two solenoids and received them. Thank you. Unfortunately, one of these valves 89-9861 has a tear in it. Can you ship me a replacement?

A shopper on Jul 14, 2012
I have a Toro 3/4" electric sprinkler valve model 53285 that uses a replacement valve diaphragm model 53349. Can the Toro 89-9861 replacement diaphagm be used instead of the model 53349. If not, can you suggest what can be used or should I replace the valve itself? Thank you in advance,
melvin q on Jun 22, 2012
I have asked a question got a response. That did not work. Tried to ask another question. Was told to verify my email address. I did that but can not ask another question?
Bill H on Jun 18, 2012
Hello, I have toro 284-15-04 zones valves. I believe this is the part need but I am not 100% sure-is this the part for this zone valve? Also is this what I need if water is getting by the zone valve without the zone being called on by the controller? No zones being called and water is getting by at least one of the zone valves. I took all apart and no dirt or debris in body. Thanks, Ron Lavoie
ron l on Apr 27, 2013
BEST ANSWER: Ron, I have replaced all of these valves and that did the trick. The old ones look fine but when you compare them to the new ones, the old ones are rubbery and not as stiff anymore. Cleaning them also works for awhile and spraying silicone on them helps. However, getting new ones should solve your problem. Make sure the spring inside is still good also.
