If you're just needing the handle part of your waste valve then you should be able to use either the Replacement Handle for LaSalle Bristol Cable-Actuated RV Waste Valves # 34490CMA1G which uses a screw to install, or the Replacement Handle for Bladex and Valterra Waste Valves # T1003-6MNVP which threads onto the waste valve. If you aren't sure what you have just send me some photos and I can try to help you out.
Since these handles use threads to install you shouldn't have any problems... view full answer...
