pex tubing size

I have 2011 Laredo 5er 318 RL. I need to relocate the location of my low point drain valves. What size pex tubing is used and do they use ď shark bite ď. connectors. Is there an easy way to do this . They are near the front side of the trailer and I need them at the back near the dump valves.

Most common size is 1/2Ē. Shark bite will work just fine, factory probably uses a crimp/clamp.

Can I ask why you want to relocate the drains?

note about low point drains, they must be at the low point.

trailer is parked at a seasonal site now and we have a deck at the front of the trailer.
Now I have to crawl under the trailer to get to the drains I want to run a line from the drains to the back of the trailer for easier access

1/2 inch blue or red.

hate to say this but just go to a lowes, buy the tubing, the clamps and the clamping tool ($65) and clamp the pipes. then, return the clamping tool.

Home Depot has an Apollo PEX clamp tool for $29. It works on PEX clamps from 3/8" to 3/4". I found the tool is not the "expensive part" of the system, but the clamps seem to be expensive. They work, the tool is essentially "fool proof" and most repairs (if you follow the instructions) are permanent and correctly done. Otherwise, the tool won't release from the clamp (indicating the clamp is not properly crimped)....

I'm sure Lowe's and most big box stores have similar low cost crimping tools. There's no need to buy the "professional $75 model" for the average do-it-yourself project.

FWIW I have both the cinch type and band clamp pliers. Cinch ring is easier in tight spots.

TOTALLY DISAGREE! To me that's as bad as stealing!!!! If anyone is that cheap, better not buy a rv! But you do whatever you can sleep with at night!
I also BOUGHT & KEPT the cinch clamp tool & it will work with almost any size clamp, also works to to just tighten up the existing clamps.

Agree with Danny above. Not a fan of people that do that.
Local hardware store Home Hardware will loan you the crimp tool for free with a refundable deposit. I think others do the same. YMMV
