Plumbing with pex. Tips tricks and advice, step on in .

Tell me more about the recirculating process,
The heater is gonna be 48 feet away from the bathroom .

Unless I put the large heater under the bathroom and get a small heater for the kitchen and feed it from the large heater.

Install a 3/4" retun line from the bathroom back to the water heater. Connect the return line to the cold water inlet with a check valve and pump that will pull the water back to the heater. Make sure the pump has an aqua stat built in. The pump should be 1/24th hp or less. Remeber you are moving heat not so much water.

He is on well water, as am I, but my house has pex throughout. I have a 2 stage filter for sediment, what else would you suggest?

you should not have any problems with PEX on well water.

If on well water the brass PEX fittings WILL deteriorate over time. Ask me how I know.

Yep, well water is very aggressive on metal unless you have a neutralizer on you well.

Love the Ryobi 1+ stuff. Wife took the air pump up to the mountains, inflated everyone’s floats and inner tubes at the lake.

Why does everyone use home runs with pex ?

It's for one of those tankless water heaters. Just another thing I don't want. They cost a lot of money

Going to be plumbing my garage apartment with pex .
Probably buying a cordless expansion tool and using pex A

Who has done it and what advice ya got ?

I’ve done plenty of pvc and some copper and some galvanized and some pex with shark bites in the past for repairs and small jobs .

But not new construction .

I don't see any problem using CPVC pipe and fittings. It's been around for a long time.

Yeah, plumber tried to sell me on tankless when my 10 year old 50 gallon electric unit died.
Cost of the unit, wiring, re-plumbing, it’d take at least 50 years to break even.
And that’s figuring 5 replacement quick recovery units, and the tankless going the full 50 without issues.
