Frequently Asked Questions

Yes. Flushing the unit once a year clears scale from the heat exchanger and keeps efficiency and flow steady. Skipping it in hard water shortens the lifespan considerably, which is why we cover the maintenance schedule at installation.

Usually one of three things: too many fixtures drawing at once, sediment stealing capacity inside the tank, or a unit past 10 years of service. A quick inspection at the tank tells us which cause is actually driving the problem.

Rusty hot water, popping sounds from sediment, moisture around the base, or an age past 10 years all point toward replacement. Repairs make sense on a newer unit; on tanks well past their prime they rarely buy much time.

Watch for pressure that drops without explanation, discolored water, a bill that climbs with no change in habits, or a patch of lawn that stays wet. Underground leaks erode soil and foundation material long before they show at the surface.

Bubbling paint, warped drywall, a musty smell, or mold in an odd spot usually give it away. Shut off every fixture and watch the water meter; movement with nothing running means water is escaping somewhere behind a finished surface.

Worn parts inside the tank are the usual culprit, most often the flapper or flush valve letting water seep into the bowl. Replacing those components with durable parts stops the waste and restores a clean, complete shutoff every flush.

We advise against them. Those products are caustic and slowly eat at both plastic and metal piping, turning a simple clog into pipe damage. Mechanical clearing removes the blockage safely without shortening the life of the drain line.

Soft food scraps and small amounts of waste rinse through fine. Keep out anything that expands or binds, including rice, pasta, bread, and fibrous peels, since those pack into the trap and stall the disposal motor in a hurry.

Yes. Gas work in Oregon requires a permit, a pressure test, and an inspection before the line goes into service. Stark Plumbing handles the filing, the testing, and the inspection scheduling for gas projects throughout Bend, OR and Redmond.

A sulfur or rotten egg odor is the clearest warning, along with hissing near a line, dead patches of vegetation over a buried run, or pilot lights that will not stay lit. Leave immediately and call the utility.

Yes, though some fixtures are easier than others. Sinks and showers shift readily, while a toilet needs its drain re-sloped and sometimes rerouted around floor joists. We confirm what the existing framing and drain slope allow before demolition begins.

Usually yes, with the right venting. An island sink needs a loop vent or an approved air admittance valve so the drain flows properly. The drain line also has to keep steady fall back to the main stack.

When every fixture is weak, the cause is usually upstream: a partly closed main valve, a failing pressure regulator, corrosion inside old galvanized piping, or a hidden leak in the supply line feeding the house from the street.

Insulate any line running through crawl spaces, garages, and exterior walls, disconnect hoses before the first hard freeze, and keep heat on when you travel. Stark Plumbing also winterizes vacant properties across Bend, OR and Sunriver each fall.

Repeat backups in the lowest drains, gurgling toilets, sewage odor in the yard, and unusually lush grass over the lateral all point to a break. Slow drains in several fixtures at once confirm the pattern rather than a single clog.

Once a year keeps sediment from settling at the bottom of the tank, where it steals capacity and makes the burner work harder. Homes on wells or with mineral-heavy water benefit from flushing more often than once a year.
