hi All,  I used plastic gutters, rain spouts, to carry the hot and cold pex across the bay from the utility side, I used the round pipe foam for the hot water red tubing to retain heat and not heat up the blue cold water tube,  I have a mixture of the new bend right angle pex form and the solid elbow for, my corners. the grey buteral plastic pipe Clifford if was talking about was in my house,from the 70s, it shreads pieces of plastic of microscopic size. if you have it  don't ingest any of that water. lvmci...

Water to house comes from PVC pipe in almost all areas of country are you saying PVC is just not allowed inside the house?

Distribution piping is that that supplies fixtures.  Kind of like drain line vs sewer line.  Once the water is in the house and you tap into the line it becomes distribution piping. Once the drain line exits the building (usually 2' beyond the wall) it becomes sewer line. Just odd code terms BUT the newer PVC is "usually" ok for hot water and older PVC was not so it might be acceptable some places. The code of course is the minimum standard that is acceptable to most enforcement agencies. Any state or municipality can ( when permits are required and inspections are performed ) ask for a more restrictive use of materials and standards.

Hi Clifford, polybutylene Pipes Failed, polybutene is different and confusing the names are so similarly spelled.

the 1980s, many people filed class action lawsuits against manufacturers, who settled the cases without admitting that the pipes were flawed in any way. The largest lawsuit, Cox vs. Shell Oil, resulted in the company paying almost $1 billion in damages.

Soon after polybutylene plumbing became popular, the piping began to fail without warning, causing hundreds of millions of dollars in damage to people's homes. Failure was later attributed to interaction between the pipes and chlorine in public water systems, which caused the pipes to become brittle.

I consider it dangerous to ingest after reading up on it, not harmful to wash with, but mine kept breaking, lvmci...

My Angola Coach is plumbed with CPVC, and there are almost a dozen patches in the service bay where it's been fixed.  Unbeknownst to me at the time, I also lost the city water fill line when I was up at my daughter's in Kelowna, BC during Christmas - when I went to fill the fresh water tank before Quartzsite, I ended up with 100 gallons in the tank and 300 down the gutter.  I now have some PEX sitting in the baggage bin to replace the CPVC.

If you're worried about PEX being damaged, it's easy to run 1/2" PEX inside 3/4"-ID metal tube such as EMT.

Good idea!  My city water fill line runs along the exterior back wall of the rear luggage bin from the street side almost to the curb side, thus totally exposed to the elements.  Not to mention alligators!  Thanks!   ;D

Pex is the best option out there today how long it will last is anybodies guess.I am redoing a couple of houses with Pex just because of the price the coil stuff is a major PITA to work with if I did it again it would be in sticks.

The code here says to use the copper transition out of the wall at each fixture something I didn't want to do 

LOL by the time I get finished the state of CA will come out with a test result PEX causes cancer in some rats they all ways do

Seems like there is at least some good arguments for PEX.  I guess I will order a crimp tool.

as I am a pex believer

here is a story I am sure I have told before

I helped my son replumb his last house . I told him that in all the years I have been using pex I never had a leak . so as we turned on the water after all was changed he asked why is that fitting dripping ? at 50 lbs of pressure and some DUMMY ( me ) forgot to crimp the ring ! so I grab the crimper and no more drip ?

1 thing I like about pex is you can turn the fitting at the crimp to tighten or loosen a thread on fitting with out installing a union and again no leeks ?

ps I have only used shark bits for a quick fix then latter I replace with a pex fitting and crimp rings

hope this helps

Mung you don't plan on traveling in your bus anywhere? It freezes in a lot of the country elsewhere you know. I think if you are building you would want to build something that was suitable for use anywhere.

I don't plan to travel anywhere that is below freezing, I live in Florida for a reason  :P

What is the difference in the crimp tool types?

    Vern, in another thread, someone described the two different types of clamping ring.  Some people like one, some the other.  I can't find it but it will explain the different types and how the tools for them (the tools are different for the type or ring).

Well, I am going to use PEX so you guys got me that far, I am not going to use the big nasty crimp rings, so I will just order the tool above.
