Video Transcript for LaSalle Bristol RV Sewer - Waste Valves - 34466N11AB Review

Speaker 1: Today we're taking a look at the Bristol Waste Valve for RV gray water tanks. This unit adds or replaces a valve for your RV's gray water tank. It's made from a durable ABS plastic construction. It features the inch and a half diameter passage, which allows waste water to travel freely when the valve is open.The valve easily opens and closes with a T handle that's attached to a metal shaft, so you can see there how we can see that we have complete closure. Very easy to open and close the valve. The unit does feature the appropriate seals to ensure leak-proof performance.On this side, we have the inch and a half hub that slides onto a sewer pipe, so the inner diameter there, inside edge to inside edge is about 1 7/8 to 1 15/16 of an inch.

Then on this end, we have the inch and a half spigot that slides into a sewer pipe. The outer diameter there is, again, about 1 7/8 to 1 15/16 of an inch in diameter.You will need ABS solvent cement. That is required for installation and sold separately. You can find that at etrailer.com. This product's also made in the USA.That's going to do it for today's look at the Bristol Waste Valve for RV gray water tanks..

Bristol Waste Valve for RV Gray Water Tank - 1-1/2" Diameter - Hub to Spigot - 34466N11AB

Average Customer Rating:  4.7 out of 5 stars   (19 Customer Reviews)

- 34466N11AB

The item I ordered is exactly the gray tank waste valve that I needed. This product has a generous flange on each side to facilitate connecting the part to the pipe coming from the grey tank & the pipe going to the dump connection. For anyone needing to repair a break in the grey tank pipe between the tank and the waste gate...the flange on the tank side tanks a 2” abs pipe. Txs

This was the only waste gate product with a generous flange...this made it possible to connect from what was left of the grey tank drain pipeafter it froze & cracked from the previous owner to the dump valve. Otherwise...would have needed to replace the entire grey tank. Wound up using a piece of vacuum cleaner hose to complete the repair. Hasn’t leaked a ..Txs

I had to replace the factory parts on my Grand Design because they never worked correctly. I had them “fixed under warranty several times only to be disappointed again and again. The Bristol valves have worked without a hitch. As a full time RV’er that is important. I wish the rest of the RV worked as well as the replacement dump valves.

- 34466N11AB

The product is great, installation took about 15 minutes to replace, our camper is brand new! But the valve will not close. I’m not waiting a month to have it fixed by the dealer. The shipping was a day late, not etrailers fault.

- 34466N11AB

Ordering was painless. Order verification and tracking number came when they said it would. Part came on day they said and it was the correct part. Excellent company

- 34466N11AB

Always have everything I need! Excellent service!

- 34466N11AB

It worked wonderful and is still working the way it should.

- 34466N11AB

Product was as described. It shipped quickly and arrived on time. A great place to shop for your RV needs.

- 34466N11AB

The product was exactly what they said it was and was a direct replacement for the existing valve. The cost of shipping was the only reason I gave this a 4 star... shipping was close to 25% the cost of the product and that was for ground shipping not expected.

- 34466N11AB

Really good product I was pleasantly surprised good price and look to be a name brand!

Ask the Experts about this LaSalle Bristol RV Waste Valves

    Yes you could remove the center section of the valve part # 34466N11AB and install it in place of what you may have on your Forest River Cardinal. In general these are all made to the same standard dimensions but you'd need to verify that what you have is a Bristol brand valve.

  • Recommended Replacement Sewer Valves for a Motorhome
    I have some great options to replace the sewer valves on a motorhome. The best one really depends on what exactly you have now. If they are combined or you want to combine them I recommend the Bristol Double RV Waste Valves part # 34466ND13AAR. If they are separate and you want to keep them that way then I recommend the Bristol Waste Valve part # 34466N11AB for the grey water and part # 34466N4BB for the black. I'm sure you'll need some various elbows and pipe etc. but that really comes...

  • Grey & Black Water Gate Valve Replacement
    The gate valves you are referring to usually come in 1-1/2" and 3" - most often 3". These gate valves are usually in your trailers "wet bay" and only need a short pull handle. But sometimes they are located nearer to the tank and require a long cable on the valve. For 3" valve with short handle use the Valterra # T1003VP valve For 3" valve with cable use the Valterra # T1003PBC valve For 1-1/2" with short handle use the Valterra # T1001VP valve For 1-1/2" with cable use the Bristol...
