💧 Superior Loc Line Coolant Component: Acetal Copolymer for Efficient Cooling Review

I bought these to replace the low point drain plugs on my RV. According to the packaging they are only rated for 20psi, not 100psi as stated in the product description. Since the water pressure in an RV is about 40psi, I'm not sure they can handle higher pressures without leaking. I will install them in about two weeks and check my review after the trial period.

I bought these to replace the plugs on the low point drains on our caravan. My back hurt crawling under the trailer and wrenches to unscrew the plugs. I was told the drains use 1/2 inch fittings. Now I can kneel down next to the trailer and reach out to open the valve and drain the water. Ideal! Quarter turn to open, quarter turn to close.

Cute! The "valves" are rated at 100psi. "Lines" are rated at 20psi. I use valves as the low point drain on my Lance caravan. Line pressure is 50 psi with the integrated water pump running. This is 40psi when using city water with a pressure regulator. The valves are well within specifications for this purpose. They are also lightweight, so vibrations in the lower drain lines during movement are much less than metal valves.
