Weathermatic M24E Solenoids
Weathermatic experienced a problem with the M24E solenoid relating to water penetration. They have replaced the M24E with the S20P solenoid. All of the reports I have heard on this solenoid are excellent. I recommend that you contact the company's tech service department if you are still having problems. Have you tried the Weathermatic SmartLine controller? This is a really cool product. It adjusts watering times based on the weather. They have a site about the product called www.smartline.com. A lot of water providers are giving rebates for installing a product of this type. Many of these rebates are listed on the Smartline site.
Still Losing Solenoids Left and Right
Can't let this thread die now!
When I turned my 32-valve system on early this summer, as I expected, I started losing solenoids again.
I contacted Weathermatic and they touted their new S20P solenoids and sent me a box of 32 of them, no charge. I've been putting them in as the old M24Es die. I've only had the S20Ps out there for a few weeks, but none of them have failed yet.
:confused: My biggest problem now--assuming these S20Ps really last--is replacing the solenoids without cross-threading them. You do that once and you have to replace the valve cover to get another solenoid to stay in.
Now that the new S20P is narrow enough to access the screws on either side of it, I may resort to pulling the cover, installing the new solenoid in plain site, outside of the valve box, then screwing the cover with the solenoid on as one unit, unless anyone has a more sure-fire way to get them in snug enough to operate without making that fateful last twist that ruins the valve.
S20P Failed After One Irrigation Season
I was out testing my nine zone irrigation system over the weekend here in New Jersey where we had 20+ days of rain in June. The system was not responding to controller commands 100% of the time. This morning the controller said I had a short in the master valve. After disconnecting the master valve solenoid (the new replacement version S20P) and manually opening the valve (Weatermatic 12000 Series - Silver Bullet) the system work flawlessly. The irrigation system was installed late in 2007 (Oct/Nov.) worked well in 2008 and the master valve solenoid failed at the beginning of 2009.
Gene Johnson @ Weathermatic offered to sell me a replacement under a special program for $6.30 + 9.90 S&H.
I can't say I'm impressed.
