PVC Waste Pipe Water Leak Stain
Whenever you're inspecting your plumbing waste pipe
system, you're going to be looking for discolorations and staining on
the pipes themselves. You will also be looking for water stains on other
parts of the home also, like concrete, stucco, siding, flooring, and
framing.
You will eventually train your eye to see any discoloration on any part
of the home. This is usually your first clue for water, mold and other
types of damage
The arrow is pointing to a rust colored water stain on a white plastic
pipe. White pipes usually stain easier and most stains will be easy to
find.
It looks like a loose coupling is causing the water leak. We can easily
assume this, but if you notice the silver hose clamp is clamped around
the white plastic plumbing coupling.
Home Repair Tip: Most rubber couplings are used to join to pipes
together. They shouldn't be used to join a coupling flange to a pipe.
Something like this will usually create water leaks in your plumbing
waste system. If you purchase an inch and a half rubber plumbing
coupling with two hose clamps, one at each end, there's a good chance
that this should only be used for inch and a half diameter pipes.
Don't purchase a 2 inch rubber plumbing coupling or connector and use it
for inch and a half waste pipes. Some do-it-yourselfers think that they
can tighten the hose clamp, until it wraps around the inch and a half
diameter pipe, but this usually leads to leaks in the future.
Most plastic pipes can be fixed inexpensively with the same type of
plastic pipes and fittings. I would always recommend using the same type
of plastic materials that the waste pipe is constructed from, if
possible, avoid using rubber couplings with hose clamps.
