& Answer Plumbing Pipes*
I always have trouble trying to remove old rusty pipes and fittings. How
do you do it?
Rust and mineral deposits turn some of the simplest plumbing projects
into real headache jobs. One trick I try to use is to saturate a rag with
cola and wrap it around the rusted plumbing connection. Cola contains
dilute carbonic, citric and phosphoric acids which dissolves the rust
and makes the connection easy to loosen. Penetrants such as 3-in-one high
performance penetrant or liquid wrench are products that work well and
are readily available.
Let the penetrant do the hard work for you. Use a pair of pliers to hold
the pipe steady that leads to the part you need to remove. Put a wrench
on the part being removed and twist it off. This concentrates the turning
force on the threads; so the chance of damage to the pipe is minimized.
I will need to connect a PVC drain pipe to a galvanized pipe in the wall
when I remodel my upstairs bathroom, What kind of fitting should I use?
A no hub coupling makes a quick trouble free connection. The trick to
tying the two lines together is in placing the coupling over both pipes.
The easiest way to accomplish this is to push the coupling fully onto
one pipe, then push half of the coupling onto the other pipe.
A four band clamp is slid halfway onto one pipe and folded back so that
the other pipe can be moved into place. Unfold the rubber sleeve and put
the four band clamp over it and tighten.
