Water Meter

[MasterPlumbersKeymaster]

I was looking at my brothers plumbing the other day and noticed that he has 1 1/2 inch service, but only has a 1 inch water meter. How much of a benefit would it be for him to have the proper 1 1/2 inch meter installed? His water pressure is O.K., but could always be better.

Thanks!

The installer should NEVER have reduced it 2 commerical sizes.

Full size is what was the design fixture load of the origional building and someone cant just reduce a pipe size cause they feel like it . Good luck

It depends on the gallons/minute usage that will determine the size of the water meter. The pressure drop from the meter to the building will determine the line size, of course you would not want to go with a line smaller than the meter size. If your water main pressure before the meter is low you could install a 2 inch meter and it would not help. Call your water company to find out the pressure in the main, then install a pressure gauge at some point such as a hose bibb, then open a couple of faucets in the system, if there is a large pressure drop on the gauge then you would have a flow problem. This could be from the meter in to the property. If you find no big pressure drop ( water main pressur fairly constant) about the only thing you could do is add a inline pump in the service and this may help
