<div dir="ltr">Our home was built new in 2007 and is 100% PEX with crimp rings. Not only have we not had any issues with the PEX, we survived a hard freeze with no damage and no leaks.

<br>
I plumbed my shop w/apartment (4 sinks, 1 shower, 1 tub, 1 washer, 2 toilets & 2 hose bibs)using PEX & crimp rings. It was cheap & easy. That was a year ago & I have no leaks. <br>
<br>
In my house I used some shark bite connectors on a copper pipe & it started leaking. <br>
<br>
My use is just a single point but it worked fine for me. YMMV<br>

I used PEX on my kitchen remodel in 2011. Maybe I didn't know any better but I used the crimp rings on hot and cold sides, run to the icemaker, feed to dishwasher. Everything is still intact. Only downside is that PEX under the sink isn't as pretty as copper.<br>

None of the pros seem to use crimpers for their connections, and they tell me they don’t trust crimped connections. They use something like this: <a href="https://www.amazon.com/Milwaukee-2432-22-12-Volt-Propex-Expansion/dp/B0048EJX7U/ref=sr_1_1?crid=20YNES0KKJ2KB&keywords=milwaukee+pex+expander+tool&qid=1564536668&s=hi&sprefix=Milwaukee+pex%2Ctools%2C127&sr=1-1" rel="noreferrer" target="_blank">https://www.amazon.com/Milwaukee-2432-22-12-Volt-Propex-Expansion/dp/B0048EJX7U/ref=sr_1_1?crid=20YNES0KKJ2KB&keywords=milwaukee+pex+expander+tool&qid=1564536668&s=hi&sprefix=Milwaukee+pex%2Ctools%2C127&sr=1-1</a>. There are manual versions of this for sale, but I am sure this is the way to go if you are doing a fair amount of work. <br>

At the moment when you select a hot water wash, the machine fills up at a rate of about a gallon a day. Is it just the fill hose being clogged, or the valve, or the pipes feeding it? Fun fun fun!<br>
