SFR hose

In 2 days I've had 4 leaks in 2 bays.current hoses in trough are 16 years old.SFR is blowing thru on straight runs,time to replace.Any recommendtions as to brand to use.
 
I like nylon tubing, and I don't put a check valve anywhere between the boom and the storage tank. I check things regularly enough that if a check valve at the boom fails I'll see the soap in the spot-free right away, IMO less trouble than having a blown line when a valve fails.
 
I had nylon tubing from sfr pump to supply lines in the past & replace them all do to failures on a regular basis.Maybe it was just cheap stuff from when I bought the system from A-OK.
 
It could have been poly tubing, or you could have had a problem causing the lines to burst. I've been using it for 25 years in at least 150 car washes and I've never seen it fail for no reason.

I agree with MEP! Make sure to use plastic or stainless steel fittings. SF water likes to eat away at copper and brass.
 
Use pex..... I would show you my setup but it is ugly. :) My plan was to rip out all my copper also but never did it. Cheap stuff and you can purchase it anywhere now.
 
There's a bit of difference in pressure ratings between Pex and Nylon. Most Nylon's are rated at 250psi @73° and Pex is rated at 160psi at the same temp. So depending on the pressure you need and how hot it gets in the attic, you may be better off with nylon.

My SFR uses 3/8" nylon to the tee above each bay. I run it at 150 psi and have never had an issue. Been installed over 5 years. It gets plenty hot in the attic, temps above 130° is not uncommon in the summer.
 
It is hard to compare pex which has an official rating to 1 number on KR. But I understand what you are saying. (I believe pex has a 2-3x burst rate.... (which is standard I believe) which might be what KR is posting for the nylon hose?) Pex just seems like a higher quality product.... it is hard to argue if you have seen pex before? The hose and fittings also seem a lot cheaper 1/3. (Unless there is a cheap nylon hose source?)

I have used pex for 4 years now.... I like it and have never had a problem yet. I have already used and installed nylon 10+ years ago. Nylon is fine too it was also working fine when I replaced it with the pex.... everyone uses it. I like using new products though?
 
You're exactly right! Putting a PSI rating on a product like 250psi then having a burst rating of 3-4X! That doesn't make sense to me!

Eric, I'd go with the 3/8" OD Nylon tubing.

I did a search and this was the first company link I found: http://www.uponor-usa.com/commercial-plumbing/engineer/applications.aspx

It says under Commercial plumbing: "purified water systems".

But if the pex does not work out I will just have to replace it? I go to my wash all the time. I will know when it fails. I just wanted to try something new. But I have replaced all my copper with pex at my other location and even used it as a hp pump unloader hose.

When I redo my lp hoses at my other wash I am planning on using pex. I Like it....


After looking again they sell PEX-AL which has an internal layer of aluminum in between 2 layers of pex. This brings the pressure higher.
 
You should be able to get 3/8" OD nylon tubing rated for 250 PSI working pressure for about 40¢ a foot.
