Excellent quality and I was able to adjust to 40-60psi quite easily. Adjustments were smooth and easily repeatable.

This is one of the worst things I have ever bought on Amazon.Pressure drops to 30 before it cuts in. Then cuts out at 50. Supposed to be a 40/60 switch.Had to use three layers of teflon tape to stop it from leaking. Pipe dope was useless.Switch bypass does absolutely nothing.CONTACTS ON PUMP SIDE WERE INSULATED WITH CLEAR COAT BLOCKING THE PUMP POWER. WOW! THAT TOOK A LOT OF TIME TROUBLE SHOOTING THAT.No rubber grommets for wire entry.I will buy an expensive one that will be ready when this piece of junk quits on me.Update: 9-28-24, unit spontaneously quit.

Pour pompe à eau submersible.J'ai dû faire venir un spécialiste et m'à dit que cet appareil n'est pas compatible et a abîmer mon moteur de pompe dû à l'emploi.J'aimerais le retourner pour avoir un crédit.Le pressostat n'a duré que 6 semaines ensuite s'est mis à déconner. Fallait je rallume manuel environ 3 fois par jour... puis à chaque fois qu'il descendait sous 30 psi. la pression tombe à 0... il semble avoir aucune garantie.Un pro m'a dit verbalement: Avec Square D j'en aurai pour 20 ans avec usage normal... j'espère être remboursé.

This pressure switch is part of a well system and controls a 240V @ 4.7A 1/2HP pump inside of a water storage tank. The pump is responsible for 40/60 psi water to a household.It was put into service about 6 weeks ago and has worked pretty well up until about 3 weeks ago. At that point we started to get about one failure per week where the pressure dropped to 40psi, and the contacts must not have been solid so the pump did not turn on. Then as water draw from the pressure tank continued, the PSI dropped under 30, and at that point the switch requires manual intervention in order to get the pump to turn on.The end result is that inside the house, the pressure drops to ZERO and there is no more water. Not fun when taking a shower!!!Over the last 3 weeks it has gotten worse. I have inspected the contacts and seen no signs of arc'ing, spitting, or other problems. I cleaned the contacts but the problems continued to occur. So the other day I replaced this unit with another more expensive and well known brand, and this one is going into the spares box.

Worked as stated ... Had to bleed out the switch, then it worked nicely.

I prefer the manual reset type of pressure switch for my well pump. If it gets low on water when I leave a hose running, it shuts the pump off when pressure drops below 20-25 lbs. It requires manually holding the lever up until pressure builds. Far cheaper than replacing a pump.

I had 50/30 pressure switch. My new 60/40 has help increase the water pressure in my home. My pump could not handle a 70/50 but a 60/40 works great

This was an exact replacement for the original which had burned out the switch contacts. The switch mounts on a Harbor Freight sprinkler/water pump. It fit perfectly, and when operated needed no adjustment since it was already set for the 30-50psi ON/OFF operation. I'm guessing this one will last another 17 years like the first one. Great value!
