Video Transcript for Review of LaSalle Bristol RV Sewer Hose Fittings - Tank Reducer - 34466V153

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this eccentric tank reducer. This is an ABS plastic eccentric tank reducer that will convert your three inch tank outlet to a 1 1/2 inch opening for your gray water tank. This can also be used to reduce a three inch sewer pipe to a inch and a half pipe. There is no step on the inside there, so it's gonna be much easier to drain, it's not going to hold any material in the mouth of the drain port, so this is going to do a great job of connecting your three inch spigot. That spigot's gonna mount directly onto the tank outlet or will slide onto your sewer pipe, and then your inch and a half port here, our opening inner diameter is about 1 7/8 of an inch, so your inch and a half hub will slide right into your sewer pipe or over top your sewer pipe, so that all that will drain properly for you.

Now, to get this installed, you will need some ABS solvent cement, if you don't already have some of that, you can pick it up here at etrailer.com using the part number that you see on the screen there. This is made here in the USA, so you can trust it's made to the high quality standards that we've come to know and trust for products that are made here in the US. So if you are needing to reduce that three inch down to 1 1/2 inch, this is gonna be a great piece for you. That's gonna complete our look for today. Again, I'm Michael with etrailer.com, thanks for watching..
