Our house was built in the 1940's and I believe we that until today, we had the original pipes and they were galvanized. We have had problems with the shower heads and faucets getting clogged with chunks of rust. The water pressure was so bad in the house the ice maker in the refrigerator would not work properly. We also had the problem with being scalded in the shower when someone ran the water or started the washer.
Today we had the house re-piped with copper. We had a shut off valve installed right at the front of the house that way we don't have to go to the street to shut off the water. We installed a brand new 50 gallon water heater. It comes fully insulated and expected to save us more than $350.00 per year in energy. Our old water heater only held 40 gallons and was rusted out. I got a larger one, cause there are times where we would run out of hot water. With six people, including two daughters ages 18 and 20, running out of hot water wasn't a hard thing to do. Another improvement is that the water heater is strapped to the house in case of earthquake.
We now have shut off valves all over the house. We installed non-scalding technology and brand new shower heads in both bathrooms.
Tomorrow the inspector is coming to approve the work and on Tuesday, they will patch the holes needed to replace the piping.
I am so happy, I could spit!
