What is the difference between this and rainbird part # 210746-03 9 (rpk diaph) diaphram kit?
How can you tell if you need a new diaphragm? Symptoms? My system is about 12 years old.
My original diaphragm has a hole in it blocked by a white plastic plug and flat screen. I don't see that on the pictured replacement. Does it matter ?
Is the diaphragm kit pictured the one you get? This is the exact one I need and I do not need the white plastic plug.

Do it yourself, cheaper, stops leaking at head

It worked well, easy, time consuming valve box full of debris, changed 6 valves after 24 years. Recommend doing one at a time. If solenoid needs changing simple to do at same time found calcium build up/hard water on flaps. Stops leaking at head.

Perfect fit for my Rain Bird valve - I bought 5 more to have on hand

I had a Rain Bird irrigation valve that would not shut off, even after flushing. This diaphragm makes EASY work to replace the full internals of a RB valve WITHOUT having to do any PVC work - no cutting out old, splicing in new, etc.....1)ensure your irrigation system H2O supply is shut off - then simply unscrew the stainless screws on top of your existing valve, remove the diaphragm/internals and replace with the new one. Be mindful of the orientation of the new diaphragm, as it goes only one orientation correctly. I purchased 5 more to have on hand, as I've never had the valve body go bad on my RB valves. Great price as well!

Terrible delivery time

The product is just fine. The delivery was terrible - over a month to receive it so I had to order another one from a different supplier!!

Easy to install and fixed leaking.

Take screws out. Take off old diaphragm and spring. Clean up the seats on both sides of the assembly. Mine just took a little wiping with a lint free cloth. Put on the new diaphragm. I put the spring on the assembly side where the solenoid is located to make sure it was seated well and then lowered that onto the new diaphragm. I then pushed down on the top piece and put in the screws without tightening much at all. I then tightened in a start pattern until it was seated. Unscrewed the solenoid and used a pocket knife to get the old filter out and then replaced it. I then screwed the solenoid back in place.Turned on the system and then checked for leaks. There were none. Youtube has a good video for this kit as well. Just copy the part information and seach for that with adding installation at the beginning.

Easily fixed my system

OEM quality... fits and works as new

It costs a couple of dollars more than aftermarket replacements; however, by spending a few more dollars, you gain peace of mind and avoid having to be on your knees for years.

Fixes the diaphragm related leaks

It's a genuine Rainbird diaphragm that replaced a worn out Rainbird diagram and fixed the leak. It's competitively priced with fast Amazon prime delivery. I recommend it.
