Help! (insert cursing) old copper pipe is 1/32nd inch bigger than standard PEX

My husband is tearing his hair out trying to fix 3 leaks under kitchen sink in 76 Sovereign, probably busted when pipes froze.

New fittings won't attach to the copper. It's too wide, just a hair. The cursing is getting intense.

He bought PEX to replace long piece under the mid section bed, but can't hook them up.

Any suggestions? He's got his metal grinder out but thought I'd ask before somebody hurts themselves

Sounds like freeze related swelling. Remove affected copper and replace with pex. Sell the scrap copper and buy something fun for the trailer.

If the new copper fittings will not fit the old copper pipe then, like Kevin, would think that the copper is stretched from freezing. I like PEX and would replace all the copper I could get to with it.

yes, I like it!

but how to connect the PEX to the expanded copper that he can't get to?

Our AS is not a gut rehab - we're hoping to keep interior (in good condition).

A plumber friend dropped off some hardware today; hoping it works!

The water lines in our 1976 31' center bath Sovereign are accessible without removing interior components. Not all connections are easy to get too though. I am not sure about those with a rear bath layout that you have. Others with that layout may be able to offer some advice.

Hope things work out.

I was able to replace all the water lines in our '66 Safari with PEX without removing the interior, except for the easily-removable parts of the gauchos. It takes some crawling around and poking your head into places, but it can be done. It's almost always possible to push the PEX into the same hole the copper pipe came out of. Use a Dremel tool or the like to cut out the copper.

I used crimp fittings, so it took a lot of planning to get that last crimp located in a place where the crimping tool had room to work. The job is really mostly head scratchin'.

I don't regret a bit of it. The system has performed flawlessly for several years now.

For sure, draw a plan of your system before you tear out the copper. There will be a few places (ours was near the water pump) where you need to re-engineer a little. Copper will make a sharper corner than you can duplicate with PEX. Back to the head scratchin' part.

Shark Bite. I even keep some fittings extra for emergency repairs.

Tubing/Pipe

Airstream uses copper TUBING not copper PIPE, they are two different sizes. That freezing/expansion thing is a old wives tail that will not die.

Replace copper with pex and use shark bite fittings.

Call it an old wives tale if your wish but copper tubing will swell under freezing conditions and not split . I've seen it multiple times, and I've replaced tubing as a result.

Smile Swagging tool

They do make a swaging tool to form the end of a copper tube round and to the proper diameter. Copper does come in a 1/2 diameter which approximately 1/2" ID but is is actually 5/8 OD. They also make 1/2" OD tubing which is actually 1/2" OD. You might find this tool at a commercial plumbing outlet like Graingers. Cost is about $25 for set of 4 sizes 1/4" - 5/8". All you need is a hammer to make them work. These tools allow you to make the tube round or shrink the tube 1 size or expand the tube 1 size. Good luck
