Many people may ask why it is better to schedule the maintenance in spring. During winter, you’ll be using your water heater regularly. In the summer, most homes schedule their heater maintenance. Whereas in spring, the maintenance providers are not yet too busy. The market is still quiet, so getting a maintenance appointment is easier.
Scheduling maintenance in spring gets the water heater ready for the days and months when you need hot water the most.

Flush Your Tankless Water Heater
Flushing the heater is somewhat complicated. You need three short lengths of garden hose (or the hoses supplied by the manufacturer), and a 2.5-gallon bucket filled with white vinegar.
- Turn off the power (gas or electric) and the cold water supply. Next, shut off the hot water valve that delivers the hot water from the tankless heater to the house.
- Remove the valve caps slowly to relieve the pressure.
- Attach one hose to the primary or sum pump outlet, one on the cold-water isolation valve, and the last one on the hot water isolation valve. Put the ends of all the hoses into the vinegar-filled bucket.
- Open the two isolation valves. Turn on the sump pump and allow the vinegar to circulate through the heater for at least 45 minutes before throwing out the vinegar. Replace the vinegar with fresh water and let it run through the system for another five minutes.
- After the flushing process, close the purge port valves and disconnect all the hosing lines.
- Replace the valve caps and tighten any loose screws and levers on your unit.
