How do you lubricate RV holding tank valves and cables?
First, keep the rod well lubricated. When you dump a tank and the handle is pulled to the open position, simply shoot the stainless rod with a good shot of lubricant spray containing silicon or Teflon. Now “work” the valve open and closed a few times. DO NOT USE the old standby, WD-40.
Should I leave my GREY tank open?
Leaving your RV’s gray valve open when fully hooked up allows you to take long showers without worrying about dumping or filling up the gray tank. Some people recommend that you should never leave the gray valve open either, as it can allow odors from the park’s sewer system up into your RV.
What’s the best way to clean an RV waste valve?
Dave recommends applying silicon to the shaft, rather than WD-40, which will clean the grease and rid of the natural oils that help the valve slide fluidly. Likewise, to prevent gunk buildup and maintain pliable seals, you can pour vegetable oil down the drain and allow it to coat the RV waste valve.
What’s the best way to lubricate a sticky dump valve?
A password will be e-mailed to you. We’re asked often about the proper method to lubricate a sticky RV dump valve. The RVers are usually referring to the black 3-inch gate valve on their black holding tank. In some cases the 1.5-inch gray valve gets sticky over time especially if the RVer is not using his RV full time.
What do you put in black tank Lube?
For the black tank, just pour down the toilet. After getting the oil in the tanks, work the valves open an closed several times to work the oil into the gate seals until they slide easily. On ours, it took putting about 1/2 gallon of oil in each tank and running it through twice to get them loosened up real good.
What to do about sticky valve handles in RV?
Some RVers who have been flummoxed by sticky valve handles have gone a step further than the simple advice to lube it every now and then. By adding a Zerk fitting (grease fitting) to the dump valve assembly, they pump grease into the cavity around the steel rod. We’ve never tried it, and do have a couple of concerns.
