PEX replumbing diagram sanity check

Al,

Looks like a few PEXLOCK clamps fittings are on the red line from the tank. If so, how'd they work for you?

I used the Flair-It PEXLOCK for all my PEX-to-PEX connections and the kitchen isolation valves. I had planned on using it for my hot water bypass but the existing setup was in good shape. I will also be using it when I re-do the city water & freshwater tank inputs.

I found their website (I ordered directly from Flair-It) to be poor, the order to delivery timeframe was never stated, but a person did pick up the phone when I called to inquire and I eventually got a shipment tracking number.

The PEXLOCK connection seems quite tight and was very easy to accomplish with a plumber’s wrench, especially in the tight confines I originally had in the hot water heater area. No leaks on the first pressure test, which beats out the push-to-connect AKA Sharkbite fittings. I used the push-to-connects to join old and new for the shower & bath, and also for the PEX-to-metal connection on the hot water tank. The push-to-connects are a bit more finicky about any sort of sideways pressure at the fitting but they do allow rotation where the PEXLOCK does not.

I ordered most of my re-plumbing parts from PEXUniverse and they were timely, responsive, and answered email and called in questions. They also have some excellent videos on YouTube that helped teach me a lot. Kudos to them! They unfortunately didn’t carry the PEXLOCK fittings, hence the additional order directly from Flair-It.

Long answer to a short question, but hopefully it helps Gary & anyone else wading into a project like this.

Al,

I found PEXLOCK info online and luckily a nearby mobile home specialist hardware store had a selection of them. What intrigued me was tools required, Channel Lock type pliers to set and a screwdriver to unlock. I bought a small supply but haven't had a chance to use one yet.

Thanks for report.

Hmmm, looks like you can get Pexlock stuff from Lowes.

Yes, Lowe’s does carry it and I’d recommend them over the Flair-It website. My local Lowe’s didn’t stick PEXLOCK and I mistakenly believed a direct from the manufacturer purchase would work out better. I wrote up my my experience so others could make an informed choice.
