Toilets are the fixture people live with broken the longest, a handle you have to jiggle, a phantom refill in the night, a base that rocks. None of it is an emergency, but a toilet that runs wastes more water than almost anything else in the home, and a wobbling base is often a wax seal quietly failing onto the floor below.
The work divides into repairs, the fill valve, flapper, flush valve and seal that make up most complaints, and installations, setting a new toilet on a sound flange so it does not leak or rock. Both are ordinary, and both are worth doing right rather than living with.
Running, weak and leaking
A toilet that runs is almost always a worn flapper or a fill valve that will not shut off, both inexpensive parts. The refill-on-its-own that people hear at night is the same fault, water leaking past the flapper and the tank topping itself back up. It is the cheapest waste to stop in the house.
A weak flush is usually mineral buildup in the rim jets or a flapper closing too soon, not a toilet that needs replacing. A leak at the base is the one to take seriously, because it points at a failed wax seal, and water escaping under the toilet ends up in the subfloor rather than on the tile.

Repair or set a new toilet
Diagnose the complaint
Running, weak and leaking each come from a different part.
Repair the internals
Flapper, fill valve and flush valve are inexpensive, serviceable parts.
Set new ones on a sound flange
A fresh seal and a solid flange are what keep a new toilet from leaking or rocking.
Why the base leak is the one to watch
Most toilet faults are cosmetic annoyances; the leak at the base is not. A failed wax seal lets water escape under the toilet on every flush, and because it goes down rather than out, it soaks the subfloor and, in a Renton home, the crawl space below before anyone sees a drop.
That is why a rocking toilet is worth acting on. The rock breaks the seal, the broken seal leaks, and the leak rots the flange and the floor around it. Resetting it on a new seal and a sound flange stops a slow, hidden problem before it becomes a framing repair.
Renton toilet repair & installation questions
My toilet keeps running. Is that a real problem?
It wastes more water than almost any other fixture, quietly and constantly. The cause is usually a worn flapper or a fill valve that will not shut off, both cheap parts, so it is one of the most cost-effective repairs in the house.
Why is the flush weak?
Usually mineral buildup in the rim jets or a flapper that closes before the tank empties, not a toilet that needs replacing. Clearing the jets or adjusting the flapper normally restores a full flush.
Water is pooling at the base. What is that?
Most often a failed wax seal, which lets water escape under the toilet on each flush and soak the subfloor below. It is worth fixing promptly because the damage is hidden, and a rocking toilet accelerates it.
Can you install a toilet I purchased?
Yes. A customer-supplied toilet is fitted on a fresh seal and a sound flange, which is what keeps it from rocking or leaking, and the supply shutoff is checked while the work is open.
If I replace a toilet, what should I look for?
When a toilet is genuinely due for replacement, rather than a cheap flapper or fill-valve repair, it is a good moment to consider a water-efficient model and, for many households, a comfort-height bowl. But the fixture matters less than the set: a new toilet is only as good as the wax seal and the flange it sits on, so setting it level and solid on a sound flange is what keeps it from rocking or weeping later, which is where most toilet trouble actually starts.

The same fixtures visit that resets a toilet often handles a dripping tap, which is faucet repair and installation.
If the toilet is not running but draining slowly instead, that points to drain cleaning rather than a tank part.
