single lever vs. two-handle faucet
We have an on-demand water heater. Single floor house, rancher - so all fixtures are spread over the length of the house.
Three bathrooms (four fixtures) have same type two-handle (hot and cold) fixture. The water in all fixtures heats up fast and stays at the set temperature during the use. Two showers have the same single lever handle. Kitchen sink has single lever handle. The master bath tub (separate from the master shower) has double handle and gets hot water fast and keeps temp.
The master bathroom shower (furthest from the heater) (single lever) and kitchen sink (closer to the heater) (single lever) are in the opposite sides of the house. They both take the longest to heat up and cannot maintain the temp. The guest bathroom shower works fine.
What gives? Have anyone else had this problem?
