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.

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

Average Customer Rating:  4.9 out of 5 stars   (26 Customer Reviews)


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.



The valve is still working great. We love in the camper in Alaska and it made it thru the winter being opened & closed once a week. No problems at all.


Your service is great but the thing I was moody pleased with is that when I looked at it, it said"Made in America"! I was very happy to see that. I'm sick of seeing " made in China" on almost everything I purchase.


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 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.


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.


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


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.


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!


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


perfect replacment part!
easy install


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


Product fit for my application, went on easily.


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


Arrived very quickly. Installed 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

  • Replacing Gate Valves On A 2017 Little Guy T@B M@X S Travel Trailer
    Most of the time you can easily just replace the gate valve and save a bit of money but if you're wanting to just swap it all out then you'll most likely need to do a bit of modification. The gate valves can be unbolted whereas the hubs are glued into place so you'll have to find a good spot to cut them off and then determine what components to use based on the what you have. Most of the time it's much easier to use a hub fitting instead of a spigot since it can just slip over the pipe...

  • 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.

  • Best Anti-Sway Bar For 2012 Newmar Baystar 3002 of Ford F-53 Chassis
    The Roadmaster Rear Anti-Sway Bar, # RM-1139-145 that you linked to does show as a confirmed fit for the 2012 Newmar Baystar 3002 if you select the chassis in the fitguide instead of the coach manufacturer. The # RM-1139-145 is constructed of 1-1/2" diameter 4140 chromoly steel. This option does not require drilling for installation, retains the factory swaybar and fits chassis equipped with a V10 engine option.
