You should always listen to weird sounds a replace parts immediately before further damage.

8. It requires a new outlet: Generally, units are plugged into the existing outlet at home. A hot water pump recirculation pump requires a plug for the unit. Henceforth, you have to put up another outlet beneath the sink. Another alternative is using hardwire.

9. You can run out of hot water: In most cases, people complain of running out of hot water fast. This is because water mixes with sediment and minerals as it goes to the water heater. The sediment is heavier compared to water hence it sinks below the water heater tank.
