|In response to Re: LOW water pressure|
I had a home built in 1914 that had a similar combination. When I removed all the old galvanized AND lead pipes, I found that the galv. was about 40-60% shut down with rust and residue, particularly in the bottom of the pipe. I changed out to all copper. The reduction in the water line the further "downstream" from the main you go is supposed to assist in maintaining a constant pressure with flow. Going from 1/2" diameter copper to 1" galvanized won't be a huge help I don't think, only greater volume throught the pipe. : I have great water pressure in my house - EXCEPT to one shower on the main level. After following the pipes below to trace the issue - here is what I found. I have 1" copper pipe from the main shut off to the water heater. From there I have 1" copper to an area where it splits off to the different levels. From there - it sizes down to 1/2" copper (for about 2 feet)- and back to 1" galvanized pipe. I'm thinking about replacing the galvanized (maybe rusted?) but I don't understand why they put in the 1/2" copper. Could that be my problem?
