" Did the city check the psi on your side of the meter, hope so caue that's where it counts. They should be supplying at least 40 psi after the meter

Do you have a pressure regulator ? Was there water turned off to the house recently ? Any repairs to the house recently ? Back to you. Milo

No repairs

Water shutoff when meter was checked

Water shut off at the meter ? Here, make sure the valve is open all the way...

Dboy, try to answer my questions in post #2, thanks

You may need to repipe your entire house. If your pipes are galvanized and are almost 40 years old, this is very likely. To have someone come out and look in California or Southern Nevada, go to www.repipenow.com.

From the Op's post #1 "I am orignal owner feed from street is 3/4".copper house also.

" no galvanized pipes here, no dboyce either after the first post.

Copper pipes can fail after 40 years also. In the Las Vegas area, they will fail after about 10 years because the water is so harsh. They will last about 30 years in California. You should get a good plumber to take a look at your pipes. Good luck.

Nothing lasts for ever, including copper. One of the advantages of copper was that it doesn't rust as it is case with galvanized pipe. But it fails too - just like any other material.

Nowadays, copper became very expensive. We are now using PEX tubing instead of copper. It is cleaner, a bit cheaper and installation is quicker. You may save about 10-20% on installation.

Your "low pressure" problem may be Volume Problem. Some valve didn't get open all the way or yoko is stuck inside valve in close position. Happens all the time. Also, meter valve may not be open all the way...

FYI: 3/4" main line is WAY too small to fee whole house....Should be at least 1".

Let us know what you've decided to do. Back to you. Milo

I posted my comment because a mention of galvanized pipes never took place. I have seen a copper pipe have a failure in 10 years but never a systematic failure of the piping itself, leaks happen at bad sweat joints most frequently. 50-100 years would be my minimum expectation if proper thickness pipes are used and they will not cause reduced pressure just before failure. Unless djoyce comes back with more info we are debating with each other and helping no poster.

Hello Safedollar,

Welcome to this website.

Dboyce,

The two Best and experienced Plumber (Ballengerb1 and Milo) has given you excellent advices, and I am glad that you discovered the leak, good luck.

John

Thanks John but Milo is the plumber, I'm just a handyman installer

Hello Bob, Whatever you are great, I have learned a lot from you guys (Tom wish him quick recovery, Mark, Milo, and some others), wish you all the best, Thanks.

Best Regards,
John

A slab leak in a copper pipe is usually from flexible, thin walled flexible copper pipe being installed, then the concrete poured over it. This is a common problem we encounter. People will often patch one occurrence only to have it happen again and again. If this is the case, the solution will be to repipe, running new pipes through the walls and bypassing the slab altogether.

I hope this isn't the case with you. Good luck.

Question from amateur: When pipe is installed below a slab, I thought it was supposed to be protected from the concrete, either by being buried a few inches in dirt or by being routed through plastic. Is that sometimes not done?

No jlisenbe that is how we do it, buried in gravel and then concrete. We never pour directly on pipe, supply or drain.

Yes it is protected, but when thin walled copper tubing is used, it can kink where it is bent and this can eventually lead to failure.
