Review on 🛠️ Optimized Camco RV Water Heater Drain Plug and Wrench Kit - Specially Designed for RV & Camper Water Heater Drain Plugs, Compatible with 7/8" & 15/16" Drain Plugs , Angled Design for Easy Access to Tight Spots -(11633) , in Black by Jimmy Jefferson

. Every one of these plugs I've installed have expired in a year or less. One of them didn't even last three days when hot water poured out. Kamko should be ashamed to sell this stuff. Typically, the split between the threads occurs just below the hex head of this plug. The material can be either polyethylene or nylon (polyamide). This stopper is very weak because the material is inherently weak, especially for hot water, and some common man decided to save two cents of resin and make the center of the stopper HOLLOW! The cork is very thin at the root of the thread. Why, why, why do they let this rubbish be sold? And if the hex head of the plug pops off while you're tightening or trying to remove a leaking plug, removing the remaining bit in the threaded drain hole is some serious PITA. Save yourself the hassle and buy a brass NPT connector instead.
