Benicia's water hardness changes with the source. Does that change our Navien flush schedule?

It can. Start with a yearly flush and let us check the exchanger each time. If we see heavy scale after a year, we shorten the interval. If it comes out clean, yearly stays fine.

Our Southampton garage used to have a gas tank. Why does the Navien that replaced it keep locking out?

Look at the supply side first. An undersized gas line, a vent run that is too long or has too many elbows, or a blocked condensate drain will all lock out a Navien. We test each one, find the cause, and quote the fix.

Can you add isolation valves to our Navien so it can be flushed?

Yes. Service valves on the hot and cold lines let us, or you, circulate a descaling solution through the exchanger without disconnecting anything. On moderately hard water they make yearly maintenance simple and cheap.

Navien in Benicia

Navien heating and cooling in Benicia.

Benicia's water comes from the State Water Project, Lake Berryessa and Lake Herman, and its hardness moves as the mix of sources changes. On average it is moderately hard. For a Navien condensing tankless heater that means scale builds at an uneven pace, and a fixed flush schedule is a starting guess, not a rule.

Much of the town was built between 1970 and 1995, and many of those garages once held a 40 or 50 gallon tank. When a Navien NPE takes that spot, the gas line, the vent and the condensate drain all have to be right for a condensing unit. When one of them is wrong, the Navien shows it with a code. Our technician is based right here in Benicia, so Southampton, the Eastside and the West Side are close. We charge $99 to diagnose, credited toward the repair, and write the quote before any work.

Common repairs we handle.

Scale building faster in some seasons. When the source water runs harder, scale can build inside the exchanger ahead of schedule. We check the outlet temperature and flow, descale when the numbers call for it, and suggest a flush interval that fits your usage.
Condensate drain or neutralizer clogged. A condensing Navien makes acidic condensate that has to drain away. A clogged neutralizer or a drain line with a sag backs water up, and the unit shuts off with a code. We clean the neutralizer, recharge its media if needed, and fix the slope of the line.
Fan or flow sensor fouled after skipped service. When annual service is skipped, dust fouls the combustion fan and sediment coats the flow sensor. The unit hesitates, lights roughly, or reads flow wrong. We clean both, test the readings, and replace the sensor only if cleaning does not bring it back.
