If I was going to use air at all, I would not exceed 40 psi and would limit it to a few short bursts.

As for a hose to use, I'd recommend a flexible, lightweight 50' hose like this Flexzilla, or similar:

Most air hoses are rated at 300 psi, but you won't get anywhere near that with the coach air.

Thanks Jim for the hose recommendation. May I ask how you clean the gutters? Thx.

Uh oh. Did I write something more stupid than my lack of knowledge? Nah, donít answer that. I canít see my error, but after 2 weeks here at Newmar I admit I am pretty tired.

The pressure you will get from the coach air is whatever your dash air gauges show. If you want to keep the pressure down to the recommended 35 psi, you will need a pressure regulator in line with the hose, at one end or the other. As was suggested by Campin Cajun, if you don't seal the nose of the air gun (you will need one of those too) tightly against the tube, you won't get the full pressure on the PEX tube. You might be able to get away with that, but an inexpensive pressure regulator in-line would be safer.

Another option is to simply buy an inexpensive air compressor that already has a pressure regulator installed on it. That way, you can dial up a safe pressure and not worry. There are lots of small compressors that plug into household power (120 VAC) and some that use 12 VDC battery power. I carry a small Porter Cable CMB 15 compressor for just this kind of thing. And, it can be cranked to to 150 psi to air up tires too.

I haven't had to clean my gutters yet...and, I am in Montana with all those dreaded Cottonwood trees.

If/when I do, I will use the small compressor I mentioned in the previous post.

Don't forget that you will need the correct quick couplers; one male, one female. Hoses usually come with just threaded ends. The Flexzilla I suggested comes with 3/8 IPS* threaded ends, so you will need matching fittings.

*IPS = International Pipe Size; a standard measurement system for pipe fittings.

I bought a step down adapter to go on the end of a shop vac that will fit inside the duck bill and plan on vacuuming the drains clean. Any reason I shouldnít do that?

I'm in a very small minority here. I clean the drains from the roof with a garden hose and a step down reducer, 1/2 to 3/8 that I got at HD. Lift off the metal screen with a small straight blade screw driver, remove debris, place the 3/8 reducer in the drain hole, turn on the water at a low pressure, watch bad stuff come out below coach ( I catch it in a small bin I place under the drains), replace drain screens. Climb down the ladder and congratulate myself on clean drains!
I don't use compressed air because I would just be clearing the drain until the next rain when the same stuff I just blew out would plug it again.

Renee, two weeks at Newmar!! At least you get to meet nice people there.

Primefit IK2003-3 1/4-Inch NPT Garage Inflator with Air Accessory and 3/8-Inch By 50-Foot Air Hose Kit, 30-Piece

$31.54 from amazon, you might find it cheaper but this will take care of your needs, except for 2 crescent wrenches and some white teflon tape to put the fittings together.

I had good luck with a small auger. my son in law was on roof with garden hose, pulled screens off, removed debris, and used a Liquid-Plumr 1/4-in x 20-ft Music wire Drain auger. Eight dollars at some Lowes stores. Bought mine in Virginia Beach and checked the other grand kid location in Port Orchard, WA. While he was on the roof feeding the auger down, I was laying on ground holding the duck bills open. All four cleared in 45 minutes. No air needed.

Thanks TJ for the help. Can I use my Viair to do the job instead of purchasing another hose?

Sure. Just be careful with the pressure. I don't know the Viair, so don't know if you can reduce the pressure. If not, they don't press the hose tightly to the drain.
