When on high heat our dryer makes a bad burning (electrical/rubber) smell. I have replaced the belt, inspected all rollers, and cleaned the lint in the front and back. Low heat does not have (as bad) a smell. Thanks for any help.
Galvanized piping in your house is not unhealthy, do some research and you will find out for yourself.
Once you compare the difference in price, it will be easy to choose. CPVC is also easier to install and no worry about burning the house down with the torch.
as for safety i wouldnt worry the insides are probally coated with lime and calcium .thats why they tend to clog and you get no water flow as for breaking at joints thats does happen if you can afford it i would replace with copper but a cheaper way is using PEX piping its even cheaper then cpvc and instead of glue it uses clamp and is flexable
I would recomend having some additional lighting on the walking area. That will help your camera foucus better onthe subject. Try some white light lamps with low watts. Try Home Depot for cheap stuff.
most plumers in this area (new england) don't even bother with copper anymore unless they are making a small repair. everything is PEX. it's easy to work with, and much better than cpvc. it's an easy DIY job to start converting things to PEX and getting rid of the galvanized pipe. Readup on it if you're going to do it yourself. PEX uses a different design than traditional metal piping. because it's so inexpensive and flexible, and comes in 100,200 or 300 foot rolls, it usually is installed with a home run method where every cold water line runs back to a central manifold, and every hot line runs back to a central hot manifold off the water heater. i just replaced all the copper pipe in a 3 unit building. all the materials cost me under $500. (pipe, fittings and valves) and i got $700 when i brought all the copper to the junkyard.
