Hi – I have some friend who are experiencing some water flow problems, when the sprinkler system is on the and a toilet is used the toilets take forever to refill, probably 10 minutes, faucet flow is greatly reduced also. They are considering replacing their incoming 40 year old ¾†copper supply line from the meter with a new 1†line. The water company tested the out flow to the house at the meter and gave them a report saying that there was 83 psi and a flow rate of 23 gpm and gave them a report. They said the 1†line would correct their flow problems. The meter is a ¾†meter. The water company also told them that if they put in the 1†copper that they had to start it a least 5 feet away from the meter set up, so the first 10 or 11 feet of line would be the old ¾†copper. The meter sits in a cement tube and on the outflow side has a gooseneck that bend around and down and connects to the old ¾†copper line. The run to the house is probably 60’ or so. Would appreciate some input from you experts. I assumed that all of the line is equally plugged/corroded and using any portion of the old would not be the best approach. It would seem to make sense to remove the gooseneck and clean it or replace it and then connect the new line to it. Could the new 1†copper correct the flow problems when it is connected to a ¾†meter and ¾†gooseneck???? I know there is friction loss in piping but what your opinion might be. The house has 3 baths with sinks and showers and 3 toilets old 3.5 gal. dishwasher, clothes washer and utility sinks, 2 outside faucets and a sprinkling system for a small yard. They are empty nesters now. Appreciate any input I can pass onto them. Thanks - Don
