LaSalle Bristol Cable Actuated RV Waste Valve Set Screw

[jdrevalas]

I haven't been able to find the thread size, much less any information on the set screw in the LaSalle Bristol valve to tighten the stainless steel rod in place. The existing set screw has been over tightened (dealer or alike...) and now the 1/8" Allen wrench is starting to skip a bit and needs to be replaced before it is no longer removable. Any help is appreciated.

I am not sure of the size but 1/8" allen is usually 1/4-20 or similar. Have you tried a metric allen wrench, maybe 3.5mm? If metric could mean it is 6 mm threads.

Bah! I have a new/spare valve at my place, not installed and therefore readily accessible, and thought I could easily get the set screw out and measured for you. However, it looks slathered in loctight, and I cannot for the life of me get it out. I unfortunately can see why the dealer stripped the screw on yours....Sorry, but I tried. If you need any other info from my spare valve though, happy to help.

It is unlikely that these gate valves are made in the US (although I can’t confirm this) so the set screw is most likely to be metric.

Bristol has a contact number (Elkhart Indiana) that might be able to confirm set screw specs. https://www.lasallebristol.com/plumbing/bristol/
