## Description

Also Includes The Cylinder Shaped Piston Fits all Weathermatic remote control valves Light duty solenoid

Review: Excellent replacement for 26 year old M24E - I have been using a Rachio controller for about 8 years now. It reported a wiring error on one of my zones after it was on for about 10 minutes. None of our original 26 year old solenoids (Weathermatic M24E) had ever had an issue until now so I did not initially even think of the solenoid being an issue. After some research, I checked the solenoids resistance at the controller and it showed 6 ohms. All the others were showing around 32 ohms. I ordered this and it was a perfect replacement and is now working perfectly. It was extremely easy to swap out the old one. I screwed out the old and screwed in the new making sure not to overtighten as others have said. As an aside I was very impressed Rachio detected the very low resistance of the old solenoid and turned off the zone and reported a problem.
Review: Exactly what I needed, no near misses. - Prompt delivery and works like a champ.

## Questions & Answers

**Q: Are the S20P and the S20PSAK interchangeable?**
A: S20PSAK is a slightly different thread and would not tighten like the s20p

**Q: Does this include the plunger assembly or is this just the solenoid only?**
A: The solenoid assembly that we sell includes the plunger and spring. Thanks for the question!

**Q: does this replace the M24E?**
A: I have purchased to replace M24E but not tried yet

**Q: What weathermatic solenoids replace the signature 7962**
A: None, they DO NOT FIT- unless you find an adapter. 

Signature/Solo Rain/Nelson 7900 series OR Nelson or Signature 9000 Series OR  Signature 9500 Series all take the 7962 solenoid.
Nelson 7962 Solenoid is used on ALL Nelson or Signature Valves Since 1990.
