Video Transcript for Valterra RV Blow Out Plug Review

What's up everybody it's AJ with etrailercom. Today we're going to be checking out this, blow out, plug from Valterra and this one's made out of plastic and it's going to screw right in here to our city water connection. It's threaded so it'll go in there nice and easy. And this outside gives you a nice grip. Take off our rubber plug, and this is where we're going to hook up our air compressor to. Now what this does is blows out the lines in your rig, cause you don't want any standing water in there.

So if you're getting ready to winterize, it's a good idea to do this. That way. You get all the water out of there. You can put antifreeze in there for the winter or it's good to do just after every trip. I mean, you don't want any water, just sitting in your pipes.

If your pipes go down and dip, that's where the water is going to stay is in that dip, it only takes a couple of days for it to get stagnant and in a week you get some algae buildup and you don't want that in your drinking water, or you don't want to shower in that or anything. So it's a good idea to blow out your lines.Before you start running air through your lines, there's a couple of steps you have to go through to make sure your rig is ready to do that. We're going to walk through that together and go step-by-step on what you need to do. First step is when I go ahead and find your freshwater tank lever here, ours is located down there. I'm going to pull this handle and let as much water out as we can.

That way there's less in the lines. Just going to pull this and just watch it drain. Just letting most of the water out. That way when we hook up the compressor, we'll just blow out a little bit of the extra water and we'll be good.Our next step is we're going to go ahead and throw the switch for the bypass, the water heater. Now why we're doing that is we don't want to pump a bunch of water into the water heater, or if you're getting ready to winterize it, you don't want to pump a bunch of antifreeze into your water heater.

So flipping that switch bypasses it, and we're good to go. Now, ours is down here, here. Here you can see, I flipped that switch up now and so we're good to move on to the next step. Now we're going to open our valves because if we're going to pump a bunch of air in through the lines, we don't want to blow up the lines. If there's nowhere for the air to go.So we're going to start with the sink. You're probably going to get some water coming out. Well, let that drain. And you see it's already slowing down and we're going to go through one by one and go through all the valves. So we're going to do the sink in here, sink in the bathroom, we're gonna turn on the shower and even flush the toilet. And with the hot and cold, you go ahead and throw the other one to just let all the water out of both lines. Another thing to do just to be safe before we put air through the lines is go ahead and step down on a pedal or toilet here. That way it would release anything else in there before we add air. Now there's two different approaches for this. You can open up all the valves at once and blow out the lines. We're going to do them one by one.So remember the sink is open. Now we're going to attach our compressor, which I went ahead and lowered the PSI to 30. That way, there's not too much air going in there. We're not going to blow up any lines or anything like that. We want to be safe and careful with that too. I'm actually surprised about how much water is still coming out. And that we're leftover in the lines. We already pulled the tank drained it all the way down. This just shows you, you don't want this water just sitting there in your lines. We already went back and closed the valves in our kitchen sink. Now we're going to come here to the bathroom sink and open these up.Looks like not a lot is coming out this time. We got most of it in the kitchen. Next up is the shower. Same as before. Just open up both of these valve all the way. Let's see what happens. With the lines all blown out, I'm just going to come back to our fresh water tank and close the valve. And it's that easy to get your lines cleared out. That's why I recommend doing anytime you take a long trip, you come home. You might as well use it. If you're going to get this fitting that fits in there and threads nice. There was no air leaking at all. I didn't hear anything while I was using it. So you know it's going to hold up. The only thing I have against it is it's just made out of plastic. I think about the hose savers I have for my fresh water hoses and they're made out of brass because there's also plastic ones of those, but I'm worried that I'm going to drop it.It's going to crack or break or plastic is just going to wear down a lot quicker than brass. Valterra offers a couple of different options for these blow up plugs. I'm going to show you them here. This one is a combination of plastic and brass. You can see it's got the brass fitting there, but this part is still made out of plastic. Still a nice seal connection, no problems, no air leakage. The capsule, little bit different on this one too. It's more like a bicycle tire or tire on your cars. Just twist on there. Nice and tight. And then they also offer an all brass option. Now this is the one I would go with just because I know it's going to hold up. I can drop it. It's not going to bother it at all. It's got the brass fitting, just like the other one, but the whole part you screw in itself, the plug is made out of brass. So again, this gives me more confidence. It's going to last way longer, but I think that does it for a look at these blow up plugs from Valterra. I hope this helped..
