Q & A

Ask A Question

Q: I am looking at the flow switch and need to know if I could just change out the wire? Contractors ripped the wire out of the end connector from the control box.

Asked by: Bruce - 5/28/2017
A: Yes, you can just unscrew your existing flow switch out of its white pvc housing (the black plastic top with the wire coming out has a threaded connection), and then scew this new flow switch back in place, then finally connect the wire of the new flow switch to your existing control box.

Q: My message board on my salt water system says "wtr sensor open, chloronator off - no flow." Do I need a new flow switch? How long should a switch last?

Asked by: Kory - 6/23/2017
A: What model system do you have? It sounds like it might be a Hayward Aqualogic system. Flow switches typically last a long time, but it is possible for them to get damaged or fail. A saltwater chlorinator will turn itself off if it doesn't think water is running through it.

Q: Is this a 2" fitting, glue socket, both sides?

Asked by: Steve - 6/7/2017
A: That is correct. For pools with 1.5" plumbing, you simply use reducer bushings that you can get from the local hardware store.

Q: I need just the flow switch for a circu si system can I get just the switch?

Asked by: Eric Farr - 1/5/2018
A: These flow switches come packaged with the white PVC T-fitting, but if you don't need it, you can simply unscrew the switch from the fitting, then screw it in to your existing fitting that is in your plumbing.

Q: Where can I purchase a replacement flow switch and cable? Not a switch housed in PVC...just the switch. Do I have to buy the one in PVC and remove it from its housing?

Asked by: John W. - 5/9/2018
A: This flow switch is just threaded into the PVC housing. You can get it, unscrew it from the housing, and then screw it into your current housing.
