Richdel R-204 replacement diaphragm
Works perfectly to replace Richdel R-204 diaphragm so it saved replacing the entire valve. Wish you shipped directly to Canada.

Diaphrams fit and pressure is great!
Worked as planned - fit was perfect. After installing the new diaphragms and replacing solenoids, my 20-year-old system works like brand new.

Perfect replacement for old Safe-T-Lawn valves. Replaced diaphragm and solenoid

They work. Nothing more to say.
Sure beats replacing the entire valve. These valves have had several brand names over the years. Commonly sold at Home Depot or Lowes.

replacement for sprinkler system
Linda M on Jun 17, 2018
Could not find this product anywhere locally. All the vendors wanted us to purchase an entire new unit. This would have been a 2-3 day project of removing an old unit (that does not leak) and try and put on a new unit. The area of the valve was hard to get at. Just waiting for the part and I know this will be success. Put a bookmark on your computer so you can reference this web site. Put it on facebook.

my irritrol 205t 3/4 is leaking under the the solenoid plate is this common and will the a new diaphram fix the problem:?
glenn t on Oct 13, 2013
BEST ANSWER: I have replaced the diaphragm before, but only to solve a problem where the nylon screw (now stainless) at the center of the diaphragm (see picture) broke and the valve stopped working. My most recent replacement was first for the screw, then for a leak under the upper plate. My valves are over 25 years old, and it turned out that the plastic plate had small cracks at the hold down screws. So, this time it did not work.

If you had a leak, then tightened the screws without success, and if the plastic is old, I suggest buying a new valve.
A shopper on Apr 16, 2017
BEST ANSWER: No fins on this one - smooth rubber on both sides. The "fins" on yours may be due to the plastic of the valve body pressing into the soft rubber (?)
My Richdel has a # 204 this # 205 of yours looks just like mine ???
Is this so??
Thanks George
A shopper on Mar 8, 2013
BEST ANSWER: Yes. Pay attention to the holes in the diaphram, it will only fit one way. If it is indexed (1) hole off location; you will have a cronic leak and will not seal. Pay close attention and get it right!

Thanks !! George
A shopper on Mar 8, 2013
BEST ANSWER: It works just fine in the richdel 204 also known as Lawn Genie
I have a Richdell 205 APR and the screw at the bottom of the diaphragm broke. Does this diaphragm come with the screw on the bottom as well?
4 C on Jul 10, 2015
BEST ANSWER: It comes as one unit with screw in place....that is why your's is not working....suggest you buy few extra.... If one is bad, other zones on the way out...cost of shipping makes it cheaper to buy couple more now
Old one fell out and need to know which way is UP?
A shopper on May 10, 2012
BEST ANSWER: The top side of the diaphragm has a locator button the same size as the spring. The diaphragm has a locator tab that goes directly under the solenoid. Pay attention to the holes, they are not equally spaced, the holes right and left of the tab are closer than the rest of the holes. Tighten all (8)screws equally and carefully, do not over tighten. The top also has a protrusion that goes into the hole directly under the solenoid, be sure it is located in the mating hole, otherwise you may experience a leak under pressure. Check also to be sure the plunger side operates freely in the valve body. You may need to clean any rust or corrosion in order to make it move freely. Good Luck!
Does this diaphragm the correct replacement part for the Richdel model 205PR?
Michael W on Mar 8, 2015
BEST ANSWER: 205PR is not one of the model numbers I've seen in schematics (irrigationdirect's website offers diagrams that I've found useful). Threads on searches via Google don't provide much, so perhaps a phone call or chat with a tech at this site or another supplier for Richdel/Irritrol would get you a clear answer. Also basicirrigation dot com once was listed as a supplier; maybe contacting them, they could direct you. Could also be you mean APR? APR Series are Electric Combination Valves with Phillips Screw Bonnets. If that's the case and you are clear the valve is a 205 series, then, yes, this diaphragm is the correct replacement.
I have an older valve (not sure of the mfg or year, pretty old I'm guessing), but it is light green and has a 204 on top of the valve cover. Does anyone know the mfg and the replacement diaphragm assembly??
A shopper on Aug 8, 2011
BEST ANSWER: How did you keep the diaphram flat so the holes matched up with the spring pushing the diaphram down. THis deforms the diaphram so the screws don't match. OR is there a cement to hold the spring and diaphram in place. I have 205SF irritrol valves.
Does the spring go on top of the diaphragm and push it down on a Richdel valve?
A shopper on Jun 8, 2016
BEST ANSWER: As I remember, the valve is held down on the seat (closed) by the water pressure on the inlet side of the diaphragm , so the spring is there to hold it open( lift the valve off the seat) when the valve is actuated and there is no pressure difference across the diaphragm . This is how the manual operation bleeder works, when open it bleeds off the pressure on the top so the valve opens. So I think the spring has to go between the seat and the diaphragm, not on the top of the diaphragm and pushing onthe cover.
Will this work for the 713Apr 1" valve?
Viktor on Oct 5, 2016
BEST ANSWER: R713 1" is no longer manufactured. The diaphragm assembly (100232-H) will fix the problem.
One of my 3/4 Irritrol ASVs doesn't shut off when control cycles to the next circuit. It does shut off when all 4 circuits are off. What is the fix?
A shopper on Jul 30, 2017
BEST ANSWER: I would make sure the wires are ok. Sounds like power to valve is staying on. Could check with volt meter.
Is this one work on my old 25 yrs "204". .thank you .What is the right diaphragm replaced parts for old "204" in -line valve repair .?

Will this diaphragm assembly fit my old Richdel 1" valve. There numbers on the syphon cover saying it is a 1" valve with the designation "STD 1001"

Thanks for any help

Rodney E on May 12, 2011
BEST ANSWER: I replaced the diaphram on Hardee 205T valves, worked great, easy to do. Not sure about the Richdel 1" valve though.
Will this diaphram fit an old 1" Richdel valve? The only # I see on the valve assembly is STD 1001
Thanks for any help

A shopper on May 12, 2011
BEST ANSWER: I purchased this hopping it would fit an older 3/4" value and it worked fine. I don't know if the internal diaphragm size is different for a 1". My guess would be they'd be the same.
Is it compatible with genie rj asv series?
ignacio m on Dec 11, 2018

Need a replacement diaphragm for irritrol 2623dpr do you have some?
Kurt B on Jun 18, 2017
Why isn't the rubber diaphragm and the washer offered alone? the cost would be greatly reduced and seldom, if ever, is the SS nut plastic disc worn or damaged?
Patrick L on Sep 12, 2013
BEST ANSWER: Often, the reason is lower cost to manufacture the entire component rather than just a part of it. Kitchen/Bath manufacturers like Delta do the same thing. Fortunately, we have begun to arrive at successful recycling programs that can easily handle the used and replaced parts.
does this diaphragm fit the Richdel 205SF valve system?
G W on Jun 23, 2012
BEST ANSWER: YES; schematics are available online and are useful for verification.
This looks similar but not identical to the diafragm that came out of my Hardie 205S valve. Can you tell me if this fits mine? if so, can I order just the diafragm or do I need to buy the whole valve and just use the top portion?
A shopper on May 20, 2012
BEST ANSWER: 2mco dot com/Turf.php is useful for brief history on Hardie, Richdel, and Irritrol--all essentially the same. Schematics are available online (I've found irrigationdirect's website useful), and lists 205S as a Richdel model as well. This diaphragm fits Richdel/Irritrol (and therefore Hardie) 205S. Yes you can buy this product 100232-H diaphragm and not the whole valve to make repair/replacement to just the diaphragm.
replacement diaphragm for Richdel model11A (might be 11AD) 3/4" sprinkle valve. What is the correct part number and do you stock it?
A shopper on Sep 28, 2018
I have 3/4 copper values. I have one section that the sprinkler heads and drips are leaking. The 3/4 copper value is NOT leaking. My question is: What part of the value do I need to replace to stop the sprinkler heads and drips from leaking?
