Video Transcript for LaSalle Bristol RV Sewer - Waste Valves - 34466N5A Review

Speaker 1: Today, we're taking a look at a Bristol Waste Valve for RV black water tanks. This unit adds or replaces a valve for your RV's black water tank. It's made from a durable ABS plastic construction. It features a three-inch diameter passage, which allows wastewater to travel freely when the valve is open.The valve easily opens and closes with the V handle, which is attached to a metal shaft. The V handle has the angled design, which allows for an easier, more comfortable grip when using the handle. You can see how that opens and closes the valve.Now, on this end, we have the three-inch hub.

This slides onto a sewer pipe, so the inner diameter of that is about three-and-a-half inches. ABS solvent cement is required for installation and sold separately. You can find it at this end, we have the three-inch lug fitting, which allows you to connect to a bayonet fitting on a sewer hose. It does come with the bayonet style cap to cover the lug fitting when nothing's connected or when this end isn't in use. It also has the integrated strap that keeps the cap connected to the valve.The product's also made in the USA.

That's going to do it for today's look at the Bristol Waste Valve for RV black water tanks.

Customer Reviews

Bristol Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug - 34466N5A

Average Customer Rating:  4.9 out of 5 stars   (23 Customer Reviews)


These valves are exactly what I needed to do the repairs and repiping of a 26' 5th wheel. Thank you for sending them so quickly and at a great price!


I needed to replace the sewer valve on our camper because the old one leaked & the handle broke. This was the correct size and the handle is actually larger than the OEM part so should hold up better.


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.


Arrived very quickly. Installed easily.


This product is great I use it when dumping waste tanks. I have been pleased with all of purchases from etrailer.


Always happy with the products I've bought from e-trailer


It was exactly what I wanted to add a level of protection from any small leaks in my existing drain valves. No surprise puddles when I remove the cap.


Needed shorter valve for living quarters on a horse trailer. Works perfectly plenty of room to attach hose now.


Product was as advertised delivery was as promised tracking was the best I have seen on here thank you


The valve arrived as expected and sooner than expected. Thanks etrailer you are the best source for trailer related products on the planet.

I’m still satisfied

by: is a must for anyone that has a RV or camper! Their website is very easy to navigate no matter what you are looking for. I have used this site several times and each time my order was delivered perfectly.


Item as described. Very good quality. Just what I needed.


Replaced a black tank clean out gate on my Rpod. Not a job you want to have to do, but it was a relatively quick and easy installation. That was a year ago and it’s still doing what it’s supposed to do. Great quality!


Fast service!


As stated great products at low prices. Fast shipping and exactally as described! Very satisfied- thank You Again!


Product fit for my application, went on easily.


Item was exactly as advertised. I didn’t get 5 stars because the shipping process took longer than I thought it would.


Have not tried the pump yet so cannot give the full 5 stars, however everything else was great
Prompt service and everything showed up as promised
If needed, I will use your service again, Thank You


It works great and we are very happy

  • Can Handle of Lasalle Bristol Valve be Extended for Easier Access
    LaSalle Bristol valves like the # 34466N5A have extension rods you can install on them like with the part # 34466SP116734 which is 67-3/4 inches long or part # 34466SP1136 which is 36 inches long. There isn't a cable kit that would fit this valve though.

  • Is There a 3" MPT to 3" Lug Waste Water Valve Available from Bristol
    The Valterra Waste Valve for RV Black Water Tank # T50C uses the 3" MPT to 3" Lug. We do not have that 3" MPT to 3" Lug set up in the Bristol brand. We do have the Bristol Waste Valve for RV Black Water Tank # 34466N5A which uses 3" Hub to 3" Lug and would require LaSalle Bristol ABS Solvent Cement # 3447530889 to attach since it has the smooth connection. As far as how the Valterra compares to the Bristol they both have a 3" diameter passage that allows the wastewater to travel freely...
