: i am currently doing rehab on a house that has been vacant for a bit. we installed a new faucet in the bath on the second floor and there seems to be very little water pressure (already tryed the aerator to no avail). when you first turn the faucet on the pressure seems to be normal then after a second or so the water quantity and pressure slows way down. the down stairs set tub seem to have good pressure. any thoughts.
I always start at the faucet and work backwards. If you have neither hot or cold, most likely the problem is in the faucet itself. Shut off the water. Remove the cartridge/stem/ceramic disc (whatever your faucet has). Hold your hand over the faucet and have someone slowly turn on the stops and flush the faucet.
