Video Transcript for Valterra RV Sewer - Waste Valves - T18A Review

Speaker 1: Today we're taking a look at the Valterra double RV waste valve. This RV sanitation T combines an inch and a half waste valve and a three inch waste valve. It can be used as a replacement part or as an upgrade for your existing setup. The T configuration merges the flow of waste from your blackwater and gray water tanks. The valves are perpendicular to one another and each valve is able to rotate. The rotating valves offer easy access at the mounting locations.

You can position each valve at the desired angle during the installation.You can see how they can rotate 360 degrees. You can spin each one, that way you can adjust it and get it to where you need it for your application for your setup. It's a really nice design, it's got the nice easy to access T handles, which makes opening and closing each gate very easy. It also features the appropriate internal seals to ensure leak proof performance. This right here is the three inch spigot.

This slides into your RV's blackwater line. Outer diameter edge to edge right here, three and a half inches. This one right here is your inch and a half hub that slides over your gray water line. Inner diameter is one and 7/8 to one and 5/16 of an inch. Then located right here you have your three inch lug fitting that allows you to connect to a bayonet fitting on a sewer hose.

That has an outer diameter of three and a half inches.Bayonet style cap covers the lug fitting when not in use. Also, features the integrated strap to keep the cap connected so you don't misplace it or lose it. The unit itself is constructed of a durable ABS plastic construction. When installing this, you will need to use some ABS solvent cement. That is required for installation and sold separately.

It's available at etrailer.com. Another neat feature I like is that it uses gray and black T handles. That way you can easily identify the valves. So, gray water tank, black water tank. That's going to do it for today's look at the Valterra double RV waste valve.

After damaging our original, this was an exact replacement and easy enough to install using the appropriate glues. The outlet cap is much tighter that the original and really requires a universal oil filter wrench to remove and install.

exactly as advertised. both inlets rotate without any modification at all. The construction is solid and the dimensions are accurate. highly adjustable, heating the black tank outlet a bit with a heat gun made this unit slide on like butter. I used two CV joint boot Oetiker clamps of the appropriate size in the black tank inlet, instead of c-clamps.

A low driveway wipe out my dump valve. This was a exact copy replacement. I was able to replace the valve body and gate valves without cutting abs pipe. The original slip fittings matched perfectly. I'm very happy with this product.

I am Amazed, Must be my lucky day, your plastic assembly made it all the way to CA in a cardboard box, with NO packing, stuffing or any other protection, arriving in excellent condition ! Thanks!

Product was exactly what we needed to replace a cracked/leaking valve on our trailer. Easy to install and we are very pleased with the quality.

Cannot believe how easy this was - arrived in two days as promised and exactly what we needed. Unfortunately, when moving the trailer to install the fitting, we caught the black water tank on a covered rock. I know - we are very tough on exposed plumbing. Doesn't look like etrailer has those kinds of parts - too bad.

Ask the Experts about this Valterra RV Waste Valves

  • Rubber Grommet Connector Between Black Water Tanks and Waste Valve.
    This is an unexpected configutation with the valve connected directly to the black tank. Nevertheless, it seems that a Valtera # F02-2106 Replacement Rubber Grommet would fix you right up. I think I would spring for some new Valterra # H03-0018 hose clamps. If you find that you have 3-1/2" connections (rather than 3") then the Valterra # F02-2103 coupler will be needed. Otherwise you will be ready for the Valterra # T18A waste valve.

  • Dump Valve Recommendation for Fitting 3-1/2 inch and 1-1/2 inch Pipe on RV
    So based on the picture you submitted and the dimensions you listed it looks like you need a dump valve that will fit into the 3-1/2 inch pipe (3 inch spigot) and then need a 1-1/2 inch pipe ot fit over your other valve (1-1/2 inch hub). The valve setup that covers that is the part # T18A as it has a 3 inch spigot and a 1-1/2 inch hub.

  • Dual Sewer Valve Replacement for 1997 Hornet by Damon RV
    Based on the picture you sent in you'd need a sewer tee and not a wye since the angle of the two pipes is 90 degrees relative to each other in your picture. For that we have the part # T18A which would match the orientation of your pipes. I attached an install picture that shows it installed on a similar setup.

  • Differences Between Valterra Double RV Waste Valves T18, T18A, and T18C
    The differences between the three Double Waste Valves you mentioned comes down to the differences between hubs and spigots for their fittings. Hubs fit over spigots. The part # T18 has a 3 inch hub and a 3 inch spigot. The part # T18A has a 3 inch spigot and a 1-1/2 inch hub The part # T18C has a 3 inch hub and a 1-1/2 inch spigot.
