<< There is a noticeable drop when more than one faucet is on, however it's
still useable. This is a nuisance and I was wondering what I can do to fix
The very first thing you need to deal with is your supply pipe. I'd suspect
that you have an ancient 3/4" galvanized input that has gotten limed up to the
point of uselessness. If this is the case, budget for a new hookup with at leat
a 1" diameter. Copper is still the choice for many building codes, but newr
plastic materials have a lot of merit, and are far less subject to corosion and
flow-choking deposits. Good luck.
