Item Information

This Water Source Well System Pressure Switch signals the pump to start when the water system drops to 30 PSI (factory set) and stops at 50 PSI (factory set). This switch is to be used with submersible well or jet pumps. It can be wired 115-volt or 230-volt. This switch must be used in conjunction with a well pressure tank. The air pressure in the well tank, when empty of all water, must be set to 28 PSI, or the switch will not operate properly.

Rated 1 out of 5 by from Poor performance I bought this item this morning, put it in and it worked fine.....left to take care of some chores....came back 3hrs later NO WATER....Contacts were engaged and only one side was working....moved the contacts and it was single phasing our pump. Will bring it back tomorrow, doing the job twice and need to worry about damage to the pump is not a great experience.

Rated 1 out of 5 by from DO NOT BUY! BUYER Beware contacts were touching but no power was getting to the pump, which in effect allowed my aerator to run dry and my other pump that pumps water into the house to wear badly (just think buzz saw noise) since it was running dry, now just trying to squeeze every bit of life out of the pump that is less than a year old ;sad thing is the switch was less than a month old. contacts would touch no power getting through to the pump till i would smack it then the contacts would reseat and work. no questions it was the switch. do yourself a favor and buy a Square D switch.

Can I use this with the 1hp CountyLine Convertible Iron Jet Pump.

Asked by: Industrial
If the pressure switch has no bearing on the pump you purchase, it will work. What is important is if you have a 30/50 switch, you must have 28 PSI of air in your tank to make the switch work correctly. Please check the amount of air in your tank with “no water” in the tank. If you have additional questions, please call the vendor at 800-346-7611.

when should you use a 60-40 switch rather than a 20-40 or a 30-50 ?

Asked by: parr
A “40-60” switch is used with submersible pumps and larger well tanks. A 20-40 is used on jet pumps as they have a hard time building more than 50 psi. A 30-50 can be used on a jet pump or submersible. A 40/60 would not be used on a jet pump. With a 40-60 switch you get a bit more run time on the pump which is ideal.
