by:

Looks well made and seems to operate smoothly. However, it will be awhile before I get to install it and use it so I can't comment any further at this time.



by:

Fit perfect!!



by:

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.



by:

Thank you for your excellent service



by:

Boy am I Lucky, That Valve Still Works !!



by:

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.



by:

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.



by:

Was an exact replacement for my broken valve. Easy (but messy) to swap out.



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!



by:

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.



by:

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.



by:

Haven't put it on yet but looks good. Fast delivery. Good price I guess. This was easy. I like easy

by:

by:

An excellent product! Received it fast and well packaged. What's not to like?!

See what our Experts say about this Valterra RV Waste Valves

  • 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.

  • 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.

  • Replacement Waste Valve And Fresh Water Pump For A 2012 Forest River Sport Surveyor
    Hello Sandy thanks for the picture. The valve in your picture appears to be a double waste valve like the Valterra Motorhome San Tee # T18A. This valve uses a 3" spigot with a 1-1/2" hub off to the side, both of which are the standard valve sizes. You could always measure the current valve to confirm this, but based on what I can see in your picture, the # T18A will be exactly what you need. As far as a fresh water pump, they are all fairly universal, it really comes down to your requirements,...

  • 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.

  • How Are Old RV Waste Valves Removed
    You have to cut off the old valves when replacing them like with the Double RV Waste Valves - Sanitation Tee - Rotating # T18A since the solvent used to install the valves creates a permanent connection. For solvent to install the new valves we have the Valterra ABS Solvent Cement # A05-0303.

  • Replacement Double Waste Valve For A 2006 Four Winds Class C Motorhome
    The Double RV Waste Valves # T18A has a 1-1/2" spigot so you'd have to also pick up a coupling # 344633001 in order to attach it to the existing pipe. Instead I recommend the Double RV Waste Valves # T18, which comes with hub fittings so you can easily slide the existing pipes into the hubs and won't need another adapter fitting. With how your setup looks you'll most likely need to cut the 3" pipe back just a bit to fit a new double waste valve in place correctly but you'll want to be...

  • 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.
