Replacing copper with PEX


Hi All,

I'm currently demo'ing my entire basement which has the laundry room and a full bathroom. The bathroom is going to need all new plumbing and was going to use PEX for that.

My question is, should I re-do the entire basement using PEX and then sell off the copper? This would give me a chance to move around some of the lines and reduce the size of the bulkheads I would need to build.

Please let me know what you think. Do's, Don'ts, "If I had to do it all over, I would..", everything is welcomed!!

Jeff

Is there anything wrong with the pipe you have now?

OK. I think that in new construction, when you're doing everything from scratch...
that doing a layout that uses Pex can be very practical.
In remodel and reno work? Not so much.

Well, for the bathroom, that all has to come out because it was done completely wrong and will be relocated.

As for the rest of the basement, it just looks messy (even thought it will be inside the ceiling). Plus, redoing it will give me the chance to move it closer to the steel beam(s) for smaller bulk heads.

I'm also going to move and replace my hot water tank, so it could benefit there too...

Sounds like you've made up your mind.

The truth is they both do a good job. I don't think I would go out of my way to replace copper with pex, but for reasons you've stated; aesthetics, workability then it may be beneficial for you to do so. Pex is very easy to snake and fit into tight places so I think it has it's place in reno and remodel work. If your going to be doing it yourself, do the research, learn about the proper tools and do some test runs with the crimping. The connections seem to be the devil in the detail for the DIY'er when it comes to PEX.

Replacing copper with PEX


So my bias was oozing out in my typing...?

I've been trying to do some research as far as type of connections, but one thing I can't find or have yet to find is what type of diameter to use for each location (3/8, 1/2, 3/4, 1in). If anyone has any quick examples for each or any of those sizes, I would love to hear it.

Thanks again All.

Replacing copper with PEX


My house is out in the country, and we have rats all over the darn place. I wouldn't trade my copper for pex if it paid me to do it.

What size is your water service? Any idea what the static pressure is? How is the home currently plumbed and does that seem to do the job? Are you on city water or a well?

In a typical home, 3/4" mains and 1/2" supplies are the way to go.

If going with PEX you may decide to put in a manifold and home-run system.

There are many things to consider but your asking all the right questions.

Many people here beleive that Pex is the answer to everything,on the other hand I have seen too many Pex installs that look like crap.
I'm old school and love my copper pipes.
IMO It is very hard to make Pex look pretty.

I'm going to guess the water service is about 1 in. (See attached picture. It is the vertical pipe on the far right side that is NOT painted white).

I do not know the water pressure, but it is VERY good.

I am on city water and the house is currently plumbed with a mixture of copper and PVC. Everything works great the way it is, but wanted to clean up and move some of the copper in the basement, since it is now all open.
