Have bought this flow switch again and again and...

This is the best flow switch available for residential and commercial projects: straight forward installation, never a call back.

Prioritize domestic hot water

I used the flow switch to prioritize domestic hot water in a tankless water heater that also fed a hot water coil. Worked perfectly.

THE low flow switch solution

If you are repurposing a tankless water heater for zone heating and DHW with a plate heat exchanger, this is THE switch to activate the primary zone. You can set it so low you can run just a trickle from any faucet and still activate the priority DHW zone.

this switch was perfect

I needed a switch that would operate down to .12 gpm. Now when i open the facuet for my domestic water the flow switch sends a signal to a relay deactivating my zone pumps and turning on just my primary pump for domestic hot water. This switch also controls A seisco boiler and and toyo 180 boiler Works perfect evertime

Expensive, but works great.

I installed this same model for a similar application 7 years ago, and it's been working great ever since. I have it set to close at a very low flow rate, and it activates about 25 times a day. I'm expecting the same success from the new installation.

exactly what we were looking for

We needed this piece to repair our water softener system and were very pleased to find it $100.00 cheaper than other retailers close by us. It was exactly as stated and worked out great. We received in about one week. Were very happy with purchase!
