Repair It Or Replace It, Honestly
A running toilet is the most common call we get and usually the cheapest to fix. A flapper, a fill valve, or a chain sitting wrong accounts for most of them, and none of those is a reason to buy a new toilet.
Hard water is the local wrinkle. Scale builds on the flush valve seat and inside the fill valve, so a toilet that runs intermittently across San Diego County is often a mineral problem rather than a worn part, and a flapper swap alone will not settle it. In the older neighborhoods the closet flange under the bowl is frequently the original cast iron, which is worth checking before anyone bolts a new toilet down on top of it.
The honest dividing line is this. If the tank parts have failed, that is a repair. If the bowl is cracked, the toilet rocks on a failed flange, or it is an old high-volume unit costing you money on every flush, replacement starts to make sense.
A continuously running toilet wastes enough water to show up plainly on a bill, which is why it is worth fixing the week you notice it rather than the month after.
Most of these are parts, not a new toilet.
Almost always a worn flapper, a fill valve past its life, or a chain long enough to stop the flapper seating. Cheap parts, quick fix, and it stops the water waste immediately.
Mineral buildup in the rim jets, a flapper closing early, or a tank not filling to the right level. Worth checking before anyone mentions a new toilet.
A toilet blocking repeatedly is usually reporting the line beyond it rather than the bowl. That is when a camera inspection saves money.
Could be the wax ring, the tank bolts, the supply line, or a cracked bowl. Three of those four are inexpensive. The fourth is a replacement.
Movement wears the wax ring and eventually leaks under the floor. The flange beneath has usually failed, and fixing it early avoids subfloor damage.
Pre-1994 units use several times the water per flush of a modern one. If yours is original to an older house, replacement pays for itself in a way repairs do not.
If water is on the floor right now, shut the supply valve behind the toilet first.
A straight answer on when each one is right.
| Repair | Replace | |
|---|---|---|
| Running or leaking tank | Parts are inexpensive | Replacing the toilet is overkill |
| Cracked tank or bowl | Not repairable | A crack only grows |
| Rocking toilet | Usually the flange beneath | A new toilet on a bad flange still rocks |
| Pre-1994 high-volume | Repairable, but you keep the water bill | Pays back in water saved |
| Weak flush, modern unit | Usually jets or fill level | Rarely necessary |
| Repeated clogs | Camera the line first | A new toilet on a bad line still clogs |
| Remodel or accessibility | Repair if it is sound | Replace for height, style or water use |
We find what is actually wrong rather than replacing the first part that could explain it. The fix is often smaller than expected.
You get the price before work starts, parts included, and an honest read on repair versus replacement.
We complete the work, test it in front of you, and leave the area the way we found it.

Running, clogged, leaking or ready to replace. We will quote the repair before we suggest a new toilet.
A toilet that clogs repeatedly is pointing at the branch line.
