water supply line clamps?

all the supply lines are original to my 2001 Eagle. I need the change the shut off valve direction. someone installed it backwards [lever hit the floor, instead of being up].
my ? is, will small worm drive hose clamps 'squeeze' the plastic line enuf to seal it? or am I going to have to pay an RV guy to replace the crimp clamps?
any other choices?
thanks Rod in AZ

The price of the PEX clamps and tools are reasonable, and available in a lot more places. I bought a small set from Amazon in case I might need to cinch a clamp, or do a repair.

And a few PEX fittings in case I break one.

Screw type "hose clamps" don't work with PEX. When I have a leak, I usually replace the PEX with braided vinyl tubing, which does work with hose clamps. Overall it's less expensive than other types of repair methods. Also it's quicker and easier when you're on the road.

I agree with "The price of the PEX clamps and tools are reasonable, and available in a lot more places". PEX is the way to go if you use it enough to justify the cost.

Excellent post as I have a similar question. This picture is of the water intake to our Fogatti tankless water heater. The view is from under the half bathroom cabinet in our Pinnacle 36FBTS. The water line appears to be a braided type of line, not a PEX line? Yet they use the crimp clamp. It is NOT the easiest location to work on it, perhaps pull the heater out of the wall? Our leak was not coming from the clamp connection or from where the male and female ends meet. I initially thought it was and, of course in the middle of a trip. ran to Lowes to get some channel locks to get to it to unscrew and apply some plumbers tape to the male end. I managed to break one of the "wings" on the female end as it was so tight. After it still leaked and noticed it was leaking from the back of the female connector and not from the male/female connection. The female end does have a gasket built in and I was totally dumbfounded at that point and resigned to keeping a towel under it and manually turning water on/off outside when needed. I took a shower and cut water off. A bit later my bride did the same, and now no leak!!! It has remained dry ever since, and I have the wood paneling off so I can watch it, but no leaks. Dumbfounded again!!

Rod, why don't you try removing and reversing just the handle? It is screwed to the valve assembly?

The tool and rings are cheap. I bought a tool from Home Depot, for less than $15 a few years back. I bought the cheap tool used for irrigation rings.

The rings, make sure to get the ones for pex. Irrigation rings look the same, but are slightly to large for pex, and you cannot get a good clamping force.

The next time you have it disconnected, put a "cone washer" in the female connection. If it never leaks again, I would leave it alone.
Thank You, what is a cone washer?

I use PEX A and B all the time. IWISS makes a darn good tool for the clamps. If you use PEX B, use the crimp clamps. Not a fan of the pinch clamps that are in most RV's.

Saw the kit on Amazon. It had many extra clamps in 2-3 different sizes. I will go ahead and order it, thanks

... have had good luck with cone washers for that type of fitting. In addition, they usually require less torque to seat.

thanks all for the response. the braided hose sounds like a good idea. are the PEX fittings std. hose diameters?

after we get home, I am going to warm the PEX with a hair dryer, and see if I can rotate the valve.if it works and doesnt leak, OK. if it leaks, I had to fix it anyway, right.

Suspicion is purchase price of tool and clamps is MUCH, MUCH less than one Mobile tech, or one shop ticket? and MUCH, MUCH faster too?

The PEX should be standard 1/2" ID hose. Those are the fittings I ordered anyway. I haven't needed to use any yet, bought them for just in case we have a need when stores are closed, or too far away..

Rod…looks like we are neighbors. I have a PEX tool and clamps you can borrow. PM me your contact info.

I agree w/ JFlightRisk, buy the tool and do it yourself vs hiring= $30 vs ($150min?) and then in YOUR toolbox? BUT, not seeing your valve, can the HANDLE come off and be pointed differently?

What can cause a mystery leak is excessively HIGH (CG or city) WATER PRESSURE, which can exceed 120 during middle of the night sometimes, mixed w/ an aging WATER PR/ and/or possibly a spec of sand/grit on PR seat allowing slow weepage or (likely, based on your description?) a cracked plastic NUT on the female fitting; sometimes, these cracks do NOT open up until the high/ higher pressure is present? The CRACKS are CAUSED BY SOMEONE using pliers/ tools on these plastic fittings vs (hand-tight =letting the rubber seal do its job properly.) The trouble you had loosening tells me that the pliers were used at some time?

I think you are replying to me? if so, thank you. The dealer first question was what is the water pressure. It was around 50PSI if I remember correctly. He said it shouldn't be over 60PSI. What is so weird is that after messing with it for a couple of hours and a trip to the store, it mysteriously stopped!!

Jetlag, Water Pressure EFFECTS were ILLUSTRATED TO ME one day when I accidently forgot my regulator, and as soon as I turned on the faucet, RV hose/ filter connections were spraying everywhere; looking/ realizing that I forgot the regulator, I then installed without touching RV connections and turned back on... and all was amazingly LEAK FREE without any additional tightening.

no it's not squeezing the pipe enough,we have bad experience from a dealer tech,who install the small screw clamp, and the result is we have the base storage compartment all flooded. don't take chance go with the pressurizing clamp to avoid trouble
