Toilet Repair & Replacement in San Jose, CA
Toilet repair covers a toilet that is running, rocking, leaking at the base, flushing weak, or just old. Those are problems with the toilet itself, and most of them come down to a handful of parts.
Signs you need this
Test it before you call
Put a few drops of food coloring in the tank and wait 10 minutes without flushing. If color shows up in the bowl, the flapper is leaking, one of the common household leaks the EPA WaterSense program lists. Flush right after so it does not stain.
A toilet that rocks has usually worked loose at the flange, and the wax seal under it has broken. Tightening the bolts does not reseal it. It has to come up, get a new seal and be set level. Water at the base after a flush is the same job until it proves otherwise.
Tightening the bolts does not reseal a toilet that rocks.
When it is not the toilet
If the toilet gurgles when the washer drains, or water rises in the tub when you flush, the problem is downstream in the main line, and a new toilet will not fix it. A toilet that clogs again and again with normal use can also mean a partial blockage further down, which a camera inspection will show.
