Toilet repair and replacement in Sacramento, CA
A running toilet can waste more water than the rest of the house combined.

Running toilets usually need a flapper or fill valve. Rocking or leaking at the floor means the wax ring and flange need attention. We repair what can be repaired and replace toilets when the bowl, tank or design is the problem.
What toilet repair covers
Toilets are simple machines, and most problems come down to a few parts: the flapper that seals the tank, the fill valve that refills it, the wax ring that seals the base to the drain, and the flange that holds it all to the floor. We carry those parts and fix most toilets on the first visit.
When a toilet is cracked, an old high-volume model, or clogs constantly because of its design, replacement is the better value. We remove the old toilet, check the flange and the drain, set the new one level and sealed, and haul the old one away.

Toilet Repair in Sacramento: what we see locally
California only allows high-efficiency toilets to be sold new, at 1.28 gallons per flush or less. If your toilet is an older 3.5 or 5 gallon model, a replacement can noticeably cut your water bill now that Sacramento bills by meter.
Every reset gets a new wax ring and a level, solid mount so the seal holds.
In 1950s and 1960s homes across Arden-Arcade, Carmichael and North Highlands, we often find corroded cast iron flanges under the original toilets. We repair those with flange kits or replace them, so the new toilet sits on a solid base.


What you can safely do before we arrive
- Close the stop valve behind the toilet.
- Stop using the toilet if water appears at the base.
- Remove rugs and items from around the toilet.
Toilet Repair questions
Why does my toilet keep running?
Most of the time the flapper is worn or the fill valve is set too high and water is going down the overflow tube. Both are quick repairs.
Can you install a toilet I already bought?
Yes. We install customer-supplied toilets and check the rough-in measurement first so it fits.
My toilet clogs every week. Is it the toilet or the pipe?
It can be either. If plunging works but the problem returns, we run a cable or camera to check the drain before recommending a new toilet. See drain cleaning.
