The beauty of a tankless water heater is that it needs less maintenance and repair than other units. Still, there a couple of maintenance things you'll want to do on your own so that you need to contact a repair team less often. 

How Often to Maintain the Tank

The steps below are something that you should do every six months to a year, depending on how much use the tank sees. If you clean the tank and find that there was a lot of build up since the last cleaning, you might do it more often If nothing is found, you might extend the length between now and the next cleaning. 

What to Do

The most important thing to do is clean any mineral deposits that can collect in the sump pump. To do this, you will need to remove it from the unit. Get a bucket full of vinegar water ready. Submerge the sump pump and let it run in the bucket for at least 15 minutes. You may notice the water getting a little cloudier as the sump pump runs; this is a sure sign that the unit needed to be descaled to remove minerals from the insides of the pump. 

While you're at it, you will want to inspect the unit for any visible wear and tear. Problems should be reported to your tankless water heater repair specialist. 

Other Repairs to Look for

You can also look for a few small repair needs occasionally. For example, the o-ring that attaches the unit can get weak and need to be replaced. That is an easy fix that you can do yourself. You can also check the tank to ensure that there are no leaks. That is a repair that will go to a repair person. Some people like to check the temperature of the water to ensure that it is within a reasonable operating range. When the tank isn't heating the water correctly, despite it using the same amount of energy, that is an inefficiency that will continue to cost you money. 

If you notice anything strange about your water heater when doing these repairs, call a contractor. Alternately, you can leave this whole affair to a tankless water heater repair team. As long as it gets done at least once a year, you can help verify that your tank will last for a long time to come.
