What kind of water heater do you have?*

A tank stands on the floor and holds 40 to 80 gallons. A tankless hangs on the wall, about the size of a carry-on suitcase. Not sure? Pick Not Sure and we'll check on the call.

How old is it?*

Close is fine. The year is usually on the label on the side.

When was it last flushed?*

Once a year is the rule here. Most Northern Virginia water runs hard, and hard water leaves sediment in a tank and scale in a tankless.

Noticed any of these?*

Pick the one that fits best.

See what's in your tap water and how hard it is, from your water utility's own published tests. Hard water is what fills a water heater with sediment, so it tells you how often yours needs a flush.

What the visit covers.

One visit, one price, whichever kind you have. The plumbing safety check comes with both. How often yours needs it depends on your water: see the hardness by town.
