Little Giant SPRK-1 Sump Pump Diaphragm Switch Repair Kit with Casing, Black, 599300

This kit worked perfectly. The pump had been pumping up very often, before it filled. In the end, it stopped pumping up at all. Opening the pressure switch showed that the diaphragm had been stretched, I the switch seemed to be burned out. After installing the o-ring, the switch and diaphragm, the pump began pumping as expected, powering on when nearly full and doing a full pump-out prior to stopping. The pump runs quieter as it is now pumping a full volume rather than partial volumes. Excellent fix.

It fixed the problem of my pump kicking off and on continually with water in the sump. The pump is 24 years old and still going strong! The diaphragm got weak. The kit fixed the problem and the pump is running as good as always. Buy this kit, even if you don't use the housing!

My Little Giant 6-CIA kept running, and wouldn't automatically shut off like it used to. After the local plumber quoted me $875 to replace the pump, I started doing a little research. $150-200 for a new pump or $25 for this repair kit. It arrived quickly, instructions were clear (but tiny) and it requires no special tools. I figured it was worth a shot. Replacing the old parts took less than 30 minutes and the pump is working like it was new. This kit saved me at least $125 bucks and gave me some handyman cred with my family.

As anyone interested in saving money, this was a great purchase. My wife noticed our sump pump didn't shut off and unplugged it, which probably saved the pump. I ordered this and replaced the switch last weekend and the pump works just as good as new.Two items to note:1. While the instructions aren't bad, there was no good way to remove the power cable from the original switch housing. Thankfully, the old housing was in good shape and the problem turned out to be the switch itself. I was able to clean the old housing and reuse that with the new diaphram, o-ring and other pieces.2. The new diaphram causes the pump to turn on at a lower water preassure than before. My guess is the old one was turning on when the water reached a depth of about 10 inches and the new one is about 8 inches.All that said, definitely worth the money and hour it took to replace, test (just put it in a five gallon bucket and fill with your garden hose) and install back in the trap.

it works!

The pump performed well for almost 27 years with no problems. I had a French drain and sump pump installed as insurance against some unforeseen major problem with a new home. Since I had a high efficiency heater and air conditioner, the condensate pump sent its water to the sump pump area. I also had a dehumidifier in my basement which drained to the sump pump. The pump maybe operated once a day during high humidity months for one cycle of two minutes. It was not needed as a sump pump.,The pump started but did not turn off. I cleaned it, installed this kit and it operates like new. They do not call it the Little Giant for nothing. This is a high quality pump that is still supported almost thirty years later. If I had to buy the entire pump for $300, I would have. Nice to keep it working for $20.

I have bought this kit several times to repair a pump. Unfortunately, the quality of the pump has gone downhill over the last 15 years so this just adds a couple more years to a pump that is only four years old.I would recommend though it does work fine

Came with everything needed to rebuild the failed pressure switch on my Little Giant pump. Saved me lots of money over buying a new pump.
