CU301

[Rnorris1771]

Hi all! Okso I see I'm not the 1st having an issue with my Grundfus cu30. Changed the filters on my water softener, turned the water back on and no lights to my CU301?? it has power to the box. Is there a fuse somewhere I'm not seeing?

Probably just another bad CU301 controller. Try bypassing the controller and just connecting directly to 230V. If it runs turn it off quickly before the pressure gets too high. Then, go get a regular 40/60 pressure switch and you will be back in water. Of course the pump will cycle on and off with no CU301 controller, but it has probably been doing that for months before it quit completely. At least you will have water. Order a CSV1A to stop the cycling and get the strong constant pressure you should have been getting with the CU301.

CSV1A CYCLE STOP VALVE

Compare to the Competition Model CSV1A CYCLE STOP VALVE is recommended for 1 to 25 gpm and is adjustable from 15 psi to 150 psi. It is a stainless steel valve with a molded thermoplastic spring cage. It also has three additional ports (2 - 1/2" and 1- 3/4") and can be used as a pressure tank...
