Frequently Asked Questions in San Anselmo

Can a plumber help with a running toilet, or is that a DIY fix?

A running toilet usually needs a new flapper or fill valve - parts that are inexpensive and replaceable. If the toilet runs intermittently or the fill valve keeps cycling, the flapper seat may be worn or the float adjustment may be off. Roto-Rooter technicians diagnose the exact component, replace it properly, and confirm the tank seals before leaving - saving water and avoiding repeat trips.

How can I tell if my sewer main is backing up versus just one fixture clogging?

A single-fixture clog affects only that drain. A main sewer backup shows up at multiple fixtures at once - toilets gurgle when the washing machine drains, or the tub fills with water when you flush. The blockage sits between the house and the city main, so everything upstream backs up. Roto-Rooter technicians use a sewer camera to locate the exact blockage point and clear it.

How often does a septic tank need to be pumped?

Most septic tanks need pumping every three to five years, depending on household size and daily water use. Sludge and scum accumulate in the tank over time; when those layers reach the outlet baffle, solids flow into the drainfield and clog the soil pores. Roto-Rooter technicians pump the tank, inspect the baffles and lid, and note the sludge depth so you know when the next service is due.

What does a water softener actually do, and how does it work?

A water softener removes hardness minerals - calcium and magnesium - by passing water through a resin bed that swaps those ions for sodium. The resin periodically regenerates by flushing accumulated minerals with a brine solution. Softer water reduces scale buildup on water heater elements, extends appliance life, and improves soap lather. Roto-Rooter installs and sizes softeners based on household water use and hardness level.

Is plumbing service available at night or on weekends if something breaks?

Roto-Rooter dispatches technicians 24/7, 365 days a year - including nights, weekends, and holidays. A burst pipe or a sewage backup doesn't wait for business hours, and neither does Roto-Rooter's dispatch. Call 415-898-2700 any time to reach a technician and get the problem assessed before it causes further damage.

When should I consider repiping my home instead of just patching leaks?

Repeated pinhole leaks, visible corrosion, or consistently discolored water from galvanized steel pipes are signs the pipe material itself is failing. Patching individual leaks becomes a cycle that doesn't address the underlying corrosion. Roto-Rooter technicians assess the pipe material, age, and condition to determine whether targeted repairs or a full repipe to copper or PEX is the more practical long-term solution.

How do I know if I have a hidden water leak behind my walls?

Hidden leaks often show up as warm spots on the floor, discolored drywall, or a water meter that keeps moving when every fixture is off. A Roto-Rooter technician uses moisture meters and visual inspection to trace the source without unnecessary demolition. Catching a hidden leak early prevents structural damage and wasted water. Call 415-898-2700 to schedule a leak detection visit.

Why does my water heater make a rumbling noise?

That rumbling usually means sediment has settled on the tank bottom. As the burner heats water trapped beneath the layer, it pops and rolls - creating the noise. Over time, sediment insulates the element and forces the heater to work harder. Roto-Rooter technicians flush the tank, inspect the anode rod, and test the pressure relief valve to restore normal operation.

What's the difference between a regular drain snake and hydro jetting?

A cable auger cuts through or pulls out a blockage - hair, roots, grease clumps - but it doesn't clean the pipe wall. Hydro jetting sends a pressurized water jet through the line, scrubbing calcified grease, mineral scale, and root debris from the interior surface. Roto-Rooter uses camera inspection first to confirm the pipe can handle jetting pressure, then clears the line thoroughly.

My kitchen drain keeps clogging even after I use store-bought drain cleaner. Why?

Kitchen drains clog from cooking grease that cools and solidifies on the pipe wall. Chemical drain cleaners dissolve the immediate blockage but leave the grease lining intact, so the clog rebuilds within weeks. Roto-Rooter's hydro jetting scours the pipe wall with high-pressure water, removing the grease layer entirely so the drain stays clear longer. Call 415-898-2700 to schedule service in San Anselmo, CA.

What causes low water pressure throughout my whole house?

Whole-house low pressure typically points to a failing pressure reducing valve, a partially closed main shutoff, or a leak somewhere in the supply line. A single fixture with low pressure is usually a clogged aerator or shutoff issue local to that fixture. A Roto-Rooter technician diagnoses the root cause - testing the PRV, inspecting the supply line, and checking for active leaks - before recommending a fix.
