Video Transcript for LaSalle Bristol RV Sewer - Waste Valves - 34439240 Review

Speaker 1: Today we're taking a look at a waste valve body for RV blackwater tanks. This valve ads or replaces a valve for your RV's blackwater tank. Features a three inch diameter passage which allows waste water to travel freely when the valve is in the open position. We're looking at a ABS plastic valve with a stainless steel shaft; it's very strong and durable. Right here we have the nice V handle which allows for easy operation as well as a comfortable grip when opening and closing the valve. Valve body, the appropriate seals, hardware handle, all that's included and the product is made in the USA.

Now a few measurements I wanna go over with you real quick.Measuring the overall length from the bottom of the valve to the top of the handle is around ten inches. Overall width, outer edge to outer edge which is right here at the edge of the mount areas; that's about four and three eighths inches. The mount holes on this unit are all separated on center by about three and almost three and three quarters. Maybe three and eleven sixteenths of an inch. That's a square design when it comes to the mount hole pattern.

Again about three and eleven sixteenths to three and three quarter inches on center. And again mounting hardware, brand new hardware, that's all included. That's gonna do it for today's look at the waste valve body for RV blackwater tanks.

My RV black water tank drain began leaking so I searched for a replacement. I've purchased other products from etrailer before and have been satisfied. This product was delivered promptly, and it fit as advertised. Always check the return policy of vendors before ordering! 688583

Fit my 1990 HiLo camper trailer perfectly. Had to take it back off on first try and lubricate the seals on the sides that touch the valve. Without the lubricant the seal grabs the slider inside the valve so tightly that it was too hard to open and close. No instructions on package but I should have known. Not that much problem putting on or taking off. Another great buy. Have been ordering from this company for all my parts while I have been reworking this trailer I just recently purchased. etrailer.com is now the only supply company stored in my favorites on my desktop. 571886

The description of the part was very thorough and it fit perfectly. 863905

- 34439240

It worked, not much else to say about it. Oh, I should mention it’s easier to install when you put the seals on the inside of the mating parts, then you can slide the valve into place and not worry about rolling or crimping the seals. 767520

Very fast shipping. Was harder taking the part out of the package than it was to install, in other words was very easy to install and it works GREAT! Thanks 764889

- 34439240

Part exchanged with out any problems and is still working properly. If used on a daily basis, this part will need to be replaced after a year or so, as it is plastic and I do not believe it is designed to be used on a regular or continual basis. 727628

Ask the Experts about this LaSalle Bristol RV Sewer

  • How Far Apart Are the Mounting Holes on the Bristol Waste Valves
    The four bolt pattern of the flange on the waste water valves is an industry standard so you don't really have to worry about measuring the bolt hole spacing. However, to address your specific question the bolt holes are spaced 3.73" apart but depending on how exact you were measuring, you could get anywhere from 2-5/8" to 2-3/4" as its hard to get the exact center of each hole. Therefore, the Bristol Waste Valve Body for RV Black Water part # 34439240 will work for you just fine. The only...

  • Replacement Black Water Tank Outlet Valve for 2008 Keystone Cougar RV
    According to my LaSalle/Bristol representative, neither the valve size itself nor the spacing of the holes for the mounting hardware have changed over the years. The mounting holes are 3.73 inches apart center to center, which is right between 2-5/8 and 2-3/4 inches which is industry standard. The Assuming that your current valve body is for a 3 inch line, the # 34439240 you referred to will work great.

  • Is There a Black Water Tank Waste Valve Body
    The waste valve bodies alone without a hub or spigot connection are something you can get. You would need something like the Valterra Waste Valve Bodies w/ Flexible Cables for RV Black Water and Gray Water Tanks - 72" # TC1372 for both tanks or the Valterra Waste Valve Body w/ Flexible Cable for RV Black Water Tank - 72" # TC372 for the black water tank only.

  • 3 Inch Waste Valve for Black Water Tanks with a Removable Handle
    We do have a 3 inch diameter black water waste valve with a handle that unscrews but part # T1003VPM doesn't have a removable handle. Instead use part # 34439240 from LaSalle Bristol. Additionally, use part # 34466SP1112 for a 12 inch extension.
