When Plumbing Goes to AutoZone
Every now and then I look under a sink and just stop for a second.
Not because I’m confused.
Because I’m impressed.
This was one of those times.
At first glance, it almost looks like plumbing. There is a pipe going down. There is something shaped like a trap. There are hose clamps. Water probably leaves the sink and goes somewhere, which is always a nice start.
But then you look a little closer.
That is not a plumbing fitting.
That is a radiator hose.
Somewhere along the way, somebody crawled under this sink, looked at the problem, and said, “You know what this needs? A trip to the auto parts store.”
Now I have questions.
Was the plumbing aisle closed?
Was there an old Ford Ta**us parked in the driveway missing parts?
Did someone hold this hose up and say, “That’ll do”?
Did the words “universal fit” get taken way too seriously?
I’ll give credit where credit is due. It took creativity. It probably even works. A lot of strange repairs do. That is how they survive long enough for me to find them.
But just because water goes through it does not make it proper plumbing.
Sink drains are supposed to be installed with approved plumbing materials and fittings. Automotive radiator hoses are made for cooling systems in vehicles, not household drain lines. They are not intended to be permanent drain lines under a sink. Over time, they can sag, clog, deteriorate or leak.
During a home inspection, I check visible plumbing wherever I can safely access it. Most of what I find is pretty normal: loose traps, minor leaks, corrosion, poor slope, or old repairs.
Then there are days like this.
Days when a radiator hose decides it is tired of living under a hood and wants to start a new career under a sink.
I don’t know what vehicle this hose originally fit.
But I do know this:
It was not born to be a P-trap.
A plumber should repair conditions like this using proper drain materials and fittings.
Until then, somewhere out there, a car is probably wondering why it keeps overheating.
