Is this hose suitable for hot water use?

The hose at the output of my hot water tank failed. This is the third time this hose gave me trouble. It always happened when we were away from home. The first time was an improperly installed crimp ring at the indeed end that came lose and brought a flash flood in the bathroom. I replaced it with a worm gear type hose clamp from the campground store and moved on. The 2nd time was the output end crimp ring that came loose. It happened in the middle of the night. It was barely assessible with small hand and tools. We were lucky to be 15 min. away from a Walmart where I could get a small rachet and repaired with a hose clamp again.

This time it also happened near midnight. We were supposed to come home the next morning. Since we have to shut down the water system, we settled with cold water from the outside tap to wash up in the morning.

Sorry about the long-winded introduction!

The hose I took out says Valterra P/N W01-2105NSF 1/2" I.D. REINFORCED HOSE FOR POTABLE WATER 150 P.S.I. MAX WORKING PRESSURE NSF/ANSI 61 IAPMO TS 25.

I googled and found one site says this no. is a part of a pump kit. Another sells by the foot but states "FOR COLD WATER ONLY"

My question is if I replace the hose with the exact replacement, am I putting in a ticking time bomb?

I'll check out the local hardware store tomorrow to see if I can get a similar one that allow for hot water use. In the meantime, I would like to hear from some expert advice on here.

Thanks in advance!Click image for larger version

Sorry folks! I jump the gun here. I just realized the ANSI 61 IAPMO TS 25 is suitable for both hot & cold water use. I might have to go to a RV parts store tomorrow tho.

Here is some hose rate to 230 degF.

Thank you TXiceman for the suggestion!

I shopped 2 RV parts stores, a plumbing supplies store and Home Depot without success this afternoon. I might have to adapt this braided hose to the application. Only problem is that I need a few inches longer than the 24" stock and had to shop for connectors at both ends to suit this hose. It's a little challenging to work within the confined space to modify the original plastic piping especially I'm not experienced with these plastic fittings.

You might want to look at this spec sheet. It says it's only rated to 125 F which may be pretty close to your hot water temperature. Good luck.

Thank you for the lead! I found this site earlier but I couldn't proceed with ordering it.

I did found a hose supplier that has it today but the closest stock is 45 min away from the branch I made the inquiry. I will try order it online and pick up tomorrow.

You guys are so helpful! I'll keep you posted when I get my repair done.

I doubt the temperature rating is all that critical. Just use any braid reinforced hose. Even if it's hot water, the pressure in an RV is pretty low.

Water heater t-stat shuts down heating at 130*F or 140*F (Suburban/Atwood)
Pressures in WH Tank can reach 120 psi due to 'swelling' in volume of water when heated

Pressure/Temp rating are VERY Important and matter

Why is braided hose vs PEX rigid pipe being used????

This is a good question for the factory ORV. My guess is just a easy way out to use a braided hose instead of PEX. To retrofit PEX piping in a confined space would be challenging for me. It will probably take a couple of 90į elbow and another couple of 45s. And the plastic T-connectors at both ends will also need to be replaced. Therefore I thought getting a similar hose connecting with hose clamps at both ends is the simplest solution.

The hose supplier I visited today was trying to sell me a silicone braided hose @ CAD $28/ft. A 3 ft section with tax would set me back at $100+.

I might call ORV to see if they can send me a piece at a more reasonable price.

Thank you VanDiemen23 for the info! It looks like the clear hose in your bottom link suit my application the most.

However, I just placed an order with a company in NC this morning for the hose with the same Valterra P/N. They offer shipping to Canada by standard shipping @$18 vs one eBay seller quoted $42 for USPS international priority mail. The 5 ft section cost only $4.95 which is more palatable.

I shall see if it is the exact parts when it arrives. Thank you all for the response!

If it were mine, I'd replace it with PEX and simply attach those same screw on connectors. I did this on my current camper when I installed a Bidet. No clamping, crimping, or anything. It's easy and a permanent fix.
