Video Transcript for Valterra RV Blow Out Plug for Winterizing Spec Review

Today we're going to be taking a look at the Valterra RV Blow Out Plug. This plug allows for easy blow out of excess water from fresh water plumbing before winterizing. It's made from a durable plastic construction. It's white in color, and it's very easy to use. It's designed to fit a standard city water connection. What you would do is you simply screw the blow out plug into a city water fitting on the side or outside of the unit, turn off your water pumps and drain the freshwater tank.

Then you'll need to open all the RV faucets and the low point drain, and when the drain stops running you can close it up. Then close all the faucets but one and apply compressed air to the blow out plug fitting until the water stops running. You would repeat those steps or that last step with each faucet and remember to close the previously drained faucet. Be sure to include the toilet valve by pressing the foot pedal or handle. After you've done this, you're now ready to winterize your unit. That's going to do it for today's look at the Valterra RV Blow Out Plug..

Let me look into that for you!

by:
In order to blow out the water lines in our trailer last year before a winter cold snap, I had to make up a coupling for an air tank hose that I could attach to our trailer's city water inlet fitting. The one that I came up from assorted parts and materials in my garage worked, but I sure wouldn't want to have let anyone see it! When I stumbled across this one, I was impressed with its simplicity and reasonable price. I haven't used it yet, but I can tell after a careful examination that it will last for many years and save me a lot of time every time I need to purge our trailer's water lines before winter storage.
by:
This item was very useful in winterizing my self contained trailer i had been advised to get one but didn't know where to find it so when I saw it on your website I ordered it it was reasonably priced easy to order and arrived quickly all in all good experience

Use product regular and have never had an issue. Works great. Never had an issue with Etrailer or its products

by:
IT'S SIMPLE & WELL MADE! JUST A TIRE VALVE STUCK IN THE DRILLED HOLE TO BLOW OUT WATER SYSTEM. BUT...IF I WOULD HAVE THOUGHT SMARTER I WOULD HAVE MADE ONE WITH A AIR FITTING...PLUG THE AIR HOSE ON FOR CONSTANT AIR TIL ALL WATER BLOWN OUT. FORGET THOSE PLASTIC ONES.

Timely quality service
