Leak behind toilet

[Argonaut20]

I haven't had much luck with Home Depot and pex. Lowes has had rolls of 1/2" and 3/8" pex as well as a generally good supply of push on fittings. I bought a tubing cutter that looks like a big pliers with a mean blade that ratchets for $8 - $10. The cuts are square. I found the plumbing was a combination of 1/2" and 3/8" where the 3/8" was used to supply things like the wash stand and toilet and the 1/2" was used up to a branch point such as the water heater. The push on fittings are easy to use and don't leak. (So far!) No crimping with these! That crimping tool is ridiculously expensive!

I searched my closest Lowes & found that they sell "online" 1/2" pex for about $8.00/per 100' of pex(this may be an online-typo on their end) but if I can get it for this price I`m way ahead!!
I do have a copy of the Thetford/Model SL Aqua-Magic manual in case anyone is interested in it.

I read on another thread here somewhere that one guy recommended using 1/2" pex so that the fittings would end up 3/8" at the fittings..
is this possible? because when I asked at HD they said that only 1/2" & 3/4" lines were available, how would one get to 3/8" fittings?

Use a 1/2 pex angle stop,it`s outlet is 3/8 od compression-1/4 id which is supply size for the fixtures. A hand repair crimper-which will work on 2 or 4 sizes different can be found on ebay for around $30.00 and is well worth the money.The difference in fitting prices will pay for the crimper. Dave
