Most Liked Negative Review

Products great but the Quantity is wrong Beware

I have purchased this product several times and have always ordered 1 which got you 2 flanges. My most recent order I purchased 1 and they sent me 1 flange. I contacted there 800 # and they stated that it has changed and you must order 2 (there is nothing on the site to explain this). Now my job has been held up and I lost $100 in expedited shipping because supplyhouse wouldn't make good on the order.

time-saver and flexibilty

The ability to drain from either side of the valve seems like only a nice-to-have feature, until you actually need it - you can flush a boiler primary loop from both directions, properly drain a small section of piping instead of an entire loop, etc. Well worth twenty or so dollars over the non-drain versions!

Good product, but...

Looks like a well manufactured product but when attached to a B&G Ecocirc 20-18 the T-handle did not have enough clearance to operate. I considered replacing with a lever handle but ultimately returned and purchased the Webstone model with the swivel flange. I have had no issues with the swivel flange valve in operation.

Nice Product

In the current times of inferior imported products, these flanges are a welcome sight. Well made and a good value.

Is it supposed to do that?

Leaks a bit when I turn it off. Guess I got a bad one.

I replaced the circulator pump, so I ordered new isolator flanges. Had them the next day. Supply House had the lowest price. Great company, great service.

Flange gaskets must be purchased separately. They normally come with the circulator pump.
