I had a 2 inch waste valve that I installed as a greywater bypass. It has been very hard to operate, I've broke a couple of handles on it. I remembered reading a post on this board a few years ago a from someone who had put a Zerk fitting on the valve and it solved there problem. I installed one on the handle end of the valve put some grease in it and it is working great. Whoever you are thank you.
