Video Transcript for Valterra RV Sewer - Waste Valves - T40B Review

Today we're going to be taking a look at the Valterra RV waste valve. This unit is going to simply add or replace a waste valve in your RV's waste system. It's made from a strong and durable black plastic construction. It is designed for 3" diameter piping. It's going to feature a 3" hub, located on each side of the unit, so same connection point on each side. If we take a measurement of the internal diameter, measuring inside edge to inside edge, we can see that that's going to measure pretty close to 3 1/2".

External diameter is going to measure pretty close to 4". That's going to be the same for each side of the waste valve. It's going to feature the easily accessible T-handle, it's going to make opening and closing the valves quick and easy. You can see that there. Color of the handle is black. The unit is already assembled, and has the appropriate seals installed for leak-proof performance.

Uh, one last thing I just want to go over real quick is, we're going to take a measurement of the overall length with the handle in the closed position, and with it in the open position. So going this direction, we're looking at a measurement of about 9 1/2". If we go and open that up, it's going to increase pretty close to, it'll be 12 3/4 of an inch to 13", right in that area. That's going to do it for today's look at the Valterra RV waste valve.

I purchased 4 gate valves for a home-made pond filter system (the MK-2 from England). They have worked as advertised. I have had to re-apply some additional rubber caulking due to a tiny leak (not due to the gate valve). Otherwise, no complaint. If I've ever the need, I'll probably look to this gate valve again in future.


Comments
The valve effectively shuts off or allows water flow between pond filter barrels and thats exactly what its supposed to do.

I bought this to change the location of my grey water discharge to a more convenient and accessible location. It was shipped quickly and excellent quality. I'm always very happy with the products and service at etrailer.com!!

Bought 2 because we were needing to have 2 500 gallon holding tanks that could be shut off one by one. Worked perfect. Great action on valve slider. A+++

I want to use this with a portable macerator pump. The idea is if the pump jammed and I was unable to free it up, I could close this valve and remove the pump with a minimum of spillage. My valves are remote so it could get messy; hope I never need to find out how it works.

Waste valves arrived on schedule, undamaged, and as described. Valves open and close fully and seal correctly. Very happy with this purchase of 2 each 3" valves that will be used for vent control to a small hydro unit. As an owner of a trailer there is no doubt these are correct for use in your waste water system. I ordered hub to hub because my application doesn't require a hose attachment. Item#T40B

The valve has been working well and saved me a lot of money by allowing me to do the repair myself.

After picking up our trailer from warranty work on the black water tank, we took a camping trip. On the way home, we stopped to dump the tanks. When I opened the black water cap, sewerage gushed out. The service tech left the valve open. Vowing never to repeat this mess, I bought the Valterra valve. It was easy to install and I have never had this incident happen EVER again. It extends that dump pipe. So, I have to be careful boon docking, but this never became a negative issue.

Great product, but more importantly, great company! etrailer ships quickly, keeps you informed every step of the way and follows up to ensure everything was to your liking. Customer service which is sorely missed and greatly appreciated!

My existing black tank doesn't close properly th the cable mount unit. I've changed out the seal, used Calgon, etc to free up its use but to no avail. I'm adding this valve into the black line before it meets up with the gray and galley lines and allows me to manually open and close the valve securely. Easy to add by cutting out an inch of original line and using abs cement to permanently secure. I can now easily open both the galley and gray valves to equal out those tanks without the concerns of black tank contamination. Shipped quickly and on time. Great communication with the etrailer team.

This and the waste valve for RV Black Water Tank were exactly what we needed to fix the problem on our camper. It arrived a day earlier than expected and hubby had it installed with zero problems. (You do NOT want to see pictures of what precipitated the need for this product!).



- T40B
by:

I fitted this valve because the cable controlled valve I had was getting so hard to pull I thought it might brake. So i fitted this Valterra valve in a straight run of 3'' abs pipe before the grey waste outlets. So now i can get easy access to and maintain my black tank control valve.

by:

This valve was perfect for the reconfigure of my gray and black tank. With both valves being able to rotate for installation, I was able to get the position I needed. Thanks for the video showing it's features, the ease of ordering and the on time delivering!

I ordered a 3" waste valve and a 1.25" to 2" receiver for our bike rack. Both were shipped the day I ordered them and arrived a few days later in perfect condition. They were just what I needed and were priced right. You can't beat etrailers service and price.

  • Extension Handles for Valterra Waste Valves
    The best option for you to use the Valterra Bladex Waste Valve part # T40B would be to add the Extension Rod part # T1046-12VP for 6" - 11" or part # TX36HPB for 36". I cannot confirm that the handle on your Thetford valve will work with the handle on the Valterra valve. If the grey water tank on your RV has 1-1/2" diameter piping then you can use the Valterra Waste Valve part # T1001B instead.

  • How To Shorten a Valterra Sewer Handle Rod
    You have a sewer extension rod installed on your valve that is longer than you like. Therefore, all you really need to do is remove the extension and replace it with one that better matches your needs from the list below. The extensions come in a few different lengths but regardless you can look over your rod to see where the break is, hold one end with a pair of pliers, then use another pair to remove the section. It could be multiple or one long one.

  • Determining the Correct Waste Valve on RV
    I appreciate the photos but I"m not quite sure what you have under there in regards to pipe diameter. The black water tank valve will depend on if it is a hub connection, spigot connection and the diameter. For example, the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Spigot to 3" Spigot # T40A fits inside a 3" diameter pipe while the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # T40B will fit over a 3" diameter pipe. Essentially, spigot means...

  • Replacement Black Water Tank Valve For 3" Tank Pipe
    It depends on your connection with the pipe if you need a spigot to spigot or hub to hub valve. A hub connection is the female connection that accepts a spigot. The spigot is a male connection. If your existing valve slides into the 3" pipe then you need the spigot connection. The Valterra Bladex Waste Valve for RV Black Water Tank - 3" Spigot to 3" Spigot part # T40A is designed to slide into 2 separate 3" sewer pipes which sounds like what you have.
