Forum Title: Help: Water Pressure Issues After OnDemand Heater Installe3d
EDIT: Main issue solved (water shutoff wasn't turned fully on). I searched, but couldn't find an answer. After a whole house on demand water heater was installed, the pressure in all the faucets drastically drops when another faucet is turned on anywhere in the home. It might not be directly related to the on demand water heater, but thought it might be so figured I'd mention it. We're going to be installing another bathroom in the basement and this is the time to figure out and correct the water pressure issue because it's probably only going to get worse with more faucets. LAYOUT: COLD 3/4" cold coming into home 3/4" goes out to 1/2" pex for all faucets in home 3/4" goes directly into whole house on demand water heater HOT 3/4" coming out of whole house on demand heater 3/4" goes down to 1/2" pex to all faucets in home When a tap is turned on in one part of the house, all pressure is diminished in other taps as well as the original tap that was turned on. Any advice on how to correct the pressure issue? We want to install another bathroom in the basement, but need the pressure issue fixed, first. Here's what's hooked to the lines: COLD * goes into water heater * basement utility sink * washer on 1st floor * small kitchen sink 1st floor * large kitchen sink 1st floor * dishwasher 1st floor * bathroom sink 1st floor * toilet 1st floor * shower 1st floor * toilet 2nd floor * sink 2nd floor * shower 2nd floor HOT * basement utility sink * washer on 1st floor * small kitchen sink 1st floor * large kitchen sink 1st floor * dishwasher 1st floor * bathroom sink 1st floor * shower 1st floor * sink 2nd floor * shower 2nd floor The heater should be able to work with a 2-3 bathroom home, easily, according to all I read about it. Here's the unit we have: Rheem EcoSense Model # ECOH160DVLN Internet # 203404940 8.4 GPM Natural Gas High Efficiency Indoor Tankless Gas Water Heater
