Solenoid Replacement

It may, but there is no way for us to definitively know without knowing the existing valve specifications and testing it in our labs. Thank you.

Our solenoids do not have a white ring that is designed to be removed. Thank you.

That really sounds that the power supply to your times is giving up. Try a new supply, preferably with a little higher rating than what you have now

Yes, and No. Most valves nowadays are 24V AC, so their is not positive (+) or negative (-) wire to worry about. The problem is that some manufacturers use a different threading than other manufacturers to connect their solenoid to their valve. This is to ensure that you will continue to use their products when you need replacement parts. The threading is the important part. Home Depot has a great return policy if its not quite right. Try a different manufacturer. It could work. Good luck to you.

Irritol valves are usually only sold to commercial contractors. This tells me that this was probably installed by a vendor when your house was built. There is no guarantee that a retail store like Home Depot is going to have a direct replacement. The size of the valve does not matter since the solenoids are all the same size, and same voltage rating. Your going to have to try different brands of solenoids to see which one will work with the threading of your valve. The threading is the important part. All sprinkler systems that I have seen in the last 20 years all use 24V AC for signaling. Buy a couple different brands of solenoids at Home Depot. Try them out by making sure that they will screw onto the top of the valve. If they dont screw on easily, dont force it. Its plastic. You can ruin threads. Try the next one. Once you find the one that fits, then attach the wires, and return the other solenoids for a refund.

We are not familiar with that model number. Thank you.

The Richdel is a little different beasts than other valves made today. Most solenoid activated valves have the solenoid on the outside so that the solenoid is easily replaceable. Unfortunately, your going to have to replace the whole valve. I certainly hope that the original installer left enough room for you to cut the pipe below the valve and piece in the slip to thread pipe that will ultimately connect your new valve. The Rain Bird valves last about 15 years. Usually its the solenoid that has to be replaced, before the valve has to be replaced.

No, this replacement solenoid had threading issues: I had to bring 2 back to the store and replace them with seemingly intact threads, so I could seat them and screw them in this time, but......all did not screw in deep enough compared to the old solenoids on my 4 RainJet Classic RJ711 valves, so NONE could close off the valves. I'm going to have to replace my valves completely, NOT with the Lawn Genie so called replacement valves that they advertise as the exact copies of the RJ711, those replacements have bad reviews as well, bad quality control.......

Yes, my valve is a toro.

The 811 solenoids I received were made in Mexico. The original 811 solenoids from my Irritrol valve were made in the USA. The threading is different and the Mexican solenoids will NOT screw into the Irritrol valve. The photo of the 811 solenoid on the Home Depot site (when zoomed) shows a made in the USA product, which is why I ordered them...to my regret.
