What is the best hot water hose to use?

[Gary Little]

I am adding a Tiny Titian hot water heater to my Scamp during my total restoration. I purchased it at Lowes for $165.00. It holds 2.5gals pulls 11.25amps. Really heats up fast. I used the Braid PVC (1/2"ID) tubing for all pumping. But, I am having trouble getting the Hot water side to seal on the brass hose barb at the hot water side of the faucet. I think it is due to the expansion. What would be a heat rate hose to use with the hose barb that would be ok to drink from? I'll post a few pictures.

Thanks,
Gary

Gary,
That’s a good looking plumbing job. You used the same type of tubing that I would have. It looks like the tubing that I got at my local farm supply,. Do you have room to double clamp the barb that is leaking?

I would ask an company that does commerical food-preparation facilities what they would use for hot-water washdown hoses - I assume that those are potable water grade. Maybe there's a potential fit to the desire for a flexible hose for potable hot water.

Hi Craig,
Thanks for your reply. I actually got some good help today at Lowes Hardware. The plumbing guy suggested coupling to faucet supply lines together to make my 42" length needed from the water heater to the faucet. It was an additional 8 bucks but it woked great. He said it is virtually impossible to get a hose barb and clamp to seal good on the hot water side. See photo's of my progress.

Thanks,
Gary

For hot water, I would recommend the use of copper tubing. Yes, it weighs more, but leaks can kill the wood floor, which is a PAIN to replace.

Howdy, Is Pex water pipe available in the US.....this is the white poly line that uses the crimp on type fittings......possibly this type may be the best to use in RVs.....It is widly used in new home construction up here now.....Benny

The braided steel faucet hose idea was a good one. I'd not have thought of that! I probably would have used a nylon fitting with a hose barb. Screw the fitting onto the faucet inlet, then attach your hose and hose clamp. Nylon will seal to a brass faucet, and the hose and hose clamp will seal to the nylon fitting.

As Benny said, use PEX (cross linked polyethylene) tubing.

Your hardware store should have Flex Pex along with compression fittings to connect to about anything. Here's a source on line:
