LaingLHB08100086 E1-BCTNRN1W-06 EcoCirc Circulator,1/2-Inch Threaded with Thermostat and Cord

Used this to replace an existing failed circulator from the same brand that was probably 8-10 years old. Nice that it dropped right in to the old housing. The old pump was so quiet it couldn't be heard when standing next to it. Needed to touch it to see if it was running. New pump makes an annoying whine that can be heard two floors away at night. Looks like they changed the design of the impeller.Update @ 1 1/2 years. Adjusted some piping that was carrying the noise into the house structure and the whine is much less noticeable - though still louder than the original. Bumping to three stars as the pump is functioning fine other than the whine.

I've used this product before and it's quality is the reason I keep coming back.

I have one installed under my house for 10 years. a review said it would replace my old pump. I just unscrewed the old one and installed the new one and plugged it in and it works great.

Excellent product. Much better than the plastic recirculating pumps sold at major big box home improvement centers or chain hardware stores. Best to deal with guys whose main business is pumps

My plumber thought the dial was speed not temperature.

Quiet, works well, but with the ECO series, you need to buy check valves and other fittings as it's not meant for under-the-sink installation using the hot & cold supply lines the way the ACT series is.
