Replacing the Toilet Supply Line

More work with Lawrence, or I should say, byLawrence, this weekend.

Leaking RV toilet supply line

When I filled the water supply tank and turned on the pump, a beautiful sheet of water jetted out from the top of the toilet supply line. My camera could not do it justice.

The bus’s sink is plumbed from the water pump with black hose. White cross-linked polyethylene (PEX) runs from the water pump to the rear of the bus, where it inexplicably coupled to more black hose that ran up to the toilet. The black hose had split open all along the top of its curve, hence the effect above.

Lawrence has recently built a proper shower in his basement and is converting his household plumbing to PEX, so he had tubing and supplies on hand. I cut off the crimp fittings, he donated a few feet of blue PEX and more crimp fittings, and he reconnected the toilet so it no longer leaks. It can be filled with water, flushed, and everything!

Came in very handy for wringing out my dishrag while scrubbing grunge off the cookstove.


None, to me. I later saw about the same length of PEX at Graber’s Ace for $2.50; Lawrence’s would have cost less in bulk. The fittings might have been another $1-2.
