Intermatic P1131 Heavy Duty Weatherproof Above Ground Pool Pump Timer - Twist Lock Plug and Receptacle, 2 On/Off Settings - Ideal for Water Fountains, Aerators, Landscape Lighting, Pool Filter Pumps

Just like the one we've had for years! Works great! Had multiple pins for setting different times. Will use for more years to come!

I purchased this timer to use with a swimming pool pump primarily because it had a locking plug and I've been happy with Intermatic indoor timers in the past. The manufacturer's quality control on this specific product is terrible! I purchased 2 of these timers and neither would work at all. This mechanical timer uses plastic green (on) and red (off) tabs to set the desired on/off times. The tabs are supposed to engage a paddle-wheel style rotary switch. However, the green and red tabs do not engage the "paddles" on the rotary switch well enough to overcome the switch's friction and to trip the switch to either the on or off position. The timer comes with 4 red and 4 green tabs. I tried all of tabs in numerous positions on the dial. Nothing worked! I thought that maybe this was just a fluke or the result of a bad production batch, so I purchased the same timer from a different Amazon store in an effort to get a timer with a different production date and/or manufacturing facility. The second timer had the exact same problem! I purchased the Woods 50015WD Outdoor 7-Day Heavy Duty Digital Plug-in Timer with a pair of locking plug to standard plug converter adaptors (one M-F and one F-M), and a pair of outdoor extension cord safety covers. The total cost was significantly less than this Intermatic timer. The Woods timer is working great with my pool pump!

Bought this for the pool pump. I let it run for about 8-10 hours a day which is enough to keep the pool clean. Saved a ton on electricity.

I have an above ground pool with an in ground pump and filter, and I've had that set up since the original, underpowered pump and little filter gave up the ghost after a few years. I never wanted to hardwire the timer, or to pay an electrician to do it for me. I've bought a few of the regular duty Intermatic timers, and they only last a few years each. I figured it was because it's hot here in Southern California, but I new think it's because I bought an underpowered timer. This timer is for a 20 amp connection (although the ad states it's for 15 amps; it's incorrect), and my one horsepower pump should have a 20 amp connection. No wonder I've had trouble. It comes with a twist-lock outlet and needs that adapter. I bought this timer and the Coleman #09020 12/3 9" generator cord cable, as another reviewer suggested. I didn't realize that I needed the same cable with a male end as well, so that meant a trip to Home Depot. I bought the Rigid brand there, $2 more than the Coleman brand, but it has lights so you know when the circuit is on. Which it was last night, when I looked outside and realized that I left the pump on, manually. So I would recommend buying one cable from Amazon, and one from Home Depot. It's worth $2 to avoid leaving the pump on all night.

This is the third Intermatic pool timer I bought within two years. My original one lasted about 12 years then the first replacement only lasted two summers. I always bring it inside during the off season. Seems the weak part of this device is the tiny round power knob that rotates when the trippers hit it on and off. The second replacement timer I bought earlier this summer was defective and the power knob stopped turning. This third one is working ok, but I’m keeping my fingers crossed it doesn’t soon fail. If anyone can recommend a more reliable device similar to this one (with a similar twist-lock plug) let me know. For such a sturdy looking device at such a high price it should be more reliable.

Purchased this for my son's home which has an above-ground pool. The pool was set up on a timer in the basement, but this made it tricky to turn the pump on and off manually when cleaning. This timer has an on-off rotary switch under the dial. It works, but it would be much easier if it were larger. With wet hands, it's really difficult to "click" the switch just a bit to turn on and off...it often cycles on and off a couple times if you turn it too far. Otherwise, it works well, and I have the same model at my home and have had no issues with it over several years.

This worked great until we took it out of storage to use in year 3. It stopped working and just made an electrical “hum” noise. Until then we had great luck with it, but for what they’re charging the durability should have been better.

I find these timers to be hit or miss - sometimes they work, sometimes they don't. One purchased in July 2022, was either not turning off the pool pump, or not turning it on. The timer mechanism will get stuck on the pins or just spin past the pin not tripping the circuit.Now, this one, purchased June 2023, it stopped working pretty much at the 30 day mark when returns could be made. It will turn off and then not turn back on. So I was manually turning it on, knowing at least it would turn off as set. Now, fast forward another two weeks and the dial won't turn at all, it neither turns on or off.These are expensive for them to now work, and when they don't work, it costs you money in the form of your electric bill (when you want it to turn off and it doesn't work), or it costs you time in cleaning the pool when it doesn't turn on when you want it to turn on.If you have to constantly monitor it day and night, what is the point of having a timer?!Not to mention, what is the point of buying a new $90 timer every 4-5 weeks?!?

After 2 months, It’s not working anymore!
