1. What the video is about
In this video we are going to show you how to replace your water supply galvanized steel pipes to copper pipes.
What are the benefits of replacing? First, you need to know that there are three choices: steel, copper or PVC piping.
2.1. Galvanized steel
Galvanized steel pipes will rust, and can accumulate minerals and bacteria. Look at this ugly one. If you just bought a house, if you see this is wrapped around the pipe, this is a temporary fix to stop leak, it is likely it will cause problems soon.
PVC (Polyvinyl chloride) never rusts. Not this ABS type. 66% US market water supply and 75% sewer. Easy to install, use this hacksaw, solvent etc. California has restrictions. It has health risks. I have already got rid of all my food plastic containers. I am concerned the plastics might leach chemicals. I would use it only for drain and waste.
Copper. Copper is durable, bacteria-resistant, costs less and is more easily installed than steel. It requires fewer fasteners than galvanized pipes. However copper rust is poisonous. The good thing is, the poison kills the bacteria, I don’t know about people. So many people have replaced galvanized steel with copper in recent years, I guess we’ll be finding out soon!
3. If you choose copper, this is what you need
make sure to cover the ends since in the crawl space under the house it is dusty, if debris is inside the pipe, it will clog the filter at the faucet.
3.2. flexible tubes
Couplings, there are different kinds, you may go home depot to buy more than you need to reduce the number of trips there. You may return it later if unused.
3.4. Cutting tool
3.5. Lead free Solder
3.6. Lead free flux
3.7. Straps, screws
3.9. pipe wrench
4. Safety first
Safety first. Place multiple goggles in convenient places, so that you don’t have excuses not to use them. It is not worth losing your sexy eyes to save a few dollars.
