Replumbing Old House

We recently purchased an old home, (built in 1910).
I went into the crawl spae to check everything out and foudn that the plumbing is real mixture. It comes from the water meter as 3/4 inch glavanized, from there it is some galvenized, some cpvc, some flared copper. I plan on tying in to the main supply lin (3.4 inch Galv.) and replacing the rest a run at a time.
I am looking at two possibilities, 1/2 inch CPVC oe 1/2 inch PEX. What would be the recommendations? Or would you suggest something completely different?

Thanks!!

Vic

Water Pipe Replace

I would recommend 3/4 inch pex as the easiest pipe to run, if you want to use the cpvc it should be a minimum of 3/4 also.

Keep in mind if the galv. goes through the wall that will have to be replaiced sometime also. Luck.

Hi Vic,

First of all, you need to be very careful around the galvanized piping as it will be brittle at the joints. You also need to realize that the galv. pipe is probably only open about 1/2 way as it will get mineral deposits all along the inside. You will want to replace ALL possible.

The pipe sizing should be a minimum or 3/4" for the main runs and 1/2" for the branches.

As far as the type of piping used, well that depends on personal preference and If you have the tools, or are willing to purchase them.

CPVC is a good product for the homeowner to install as it only needs a hacksaw or similar to cut the pipe and glue and primer to install it.

Wirsbo/Uponor brand PEX is very good but has the most expensive tools needed. The advantage to this brand is the full size inside diameter of the fittings. You may not be able to buy this product without a plumbers lic. Some stores are like that.

Watts brand AquaPEX is also a good choice and the big box stores carry the pipe, fittings, and sell the less expensive tools. This type of PEX is slightly diminished in size at the joints as the fittings are inserted into the pipe with a crimp ring holding it together. Not usually a problem, but you may want to think of increasing the main size to 1" with this product.

Both brands of PEX products "claim" to have excellent bursting capabilities in the even of a frozen line. Don't forget to hang it quite often or it will droop and sag a lot.

And of course there is always the trusted copper tubing, soldered together, not flared, but you will need to take out a second mortgage on your home to be able to afford the price of today's copper.
