Tips to Fix a Running Toilet
Is your toilet running? (No, this is not a joke.) Running toilets are one of the most common reasons people call a plumber in Vancouver and Portland. With just a little bit of know-how, homeowners and property owners can usually handle this problem on their own.
First things first: If you have little to no plumbing experience beyond knowing how to use a plunger, it would be best to contact Simpson Plumbing. We’re providing this DIY blog post as an FYI for those who know at least a little bit about plumbing systems.
Doing plumbing work yourself — even the most basic of basics — without proper training and guidance can lead to big-time damage and more expensive problems. If you’re unfamiliar with or have no experience working on plumbing problems, a DIY blog post — even if it’s super awesome like this one! — should not be considered proper training and guidance.
OK, now that we’ve got that disclaimer out of the way …
What Problems Are Caused By A Toilet That Won’t Stop Running?
A toilet that won’t stop running is more than just a mild nuisance. It can cause a whole host of problems — including risks of flooding and water damage. If your home has a septic system, a running toilet can flood the tank — with results that can be, well, messy.
What else might happen if your toilet won’t stop running? A continuously running toilet wastes water, leading to higher water bills and a strain on our already strained environment. It also makes it more likely that there isn’t enough water in the bowl at any one time to flush properly, which can lead to clogged pipes.
How to Fix a Running Toilet
Here’s a quick checklist that should help you diagnose the problem of a running toilet. Before beginning any work, shut off the water to the toilet and drain the toilet bowl with a flush. In order to understand what follows, you might want to take a look at a basic diagram of a toilet tank assembly.
Open the tank and inspect the chain.
Sometimes the fix is super simple: The chain that holds the flapper (also known as the flush valve seal) has become caught under the flapper itself at the bottom of the tank. Jiggle the chain to free it up. Other times, the chain has a kink, meaning it’s not long enough to allow the flapper to properly seal the drain hole. Try unkinking the chain if that appears to be the problem.
Replace the flapper.
As mentioned above, the flapper (flush valve seal) is probably familiar to most people who have lifted the heavy ceramic lid off their toilet tank in order to “jiggle the chain.” It is supposed to plug up the drain hole (the flush valve drain seat; see No. 2 below) on the tank bottom. Over time, it can wear out, leading to a break in the seal. You can take the flapper to your hardware store and ask for a matching part that you can use to replace the old, malfunctioning one.
Inspect the flush valve seat.
This part of the toilet’s plumbing can also become flawed. Unfortunately, replacing this part is a bigger job — one that involves swapping out the entire flapper valve. This is one of those plumbing jobs that’s usually beyond the skills of your average everyday plumbing homeowner. Contact Simpson Plumbing for help.
Adjust the float.
The float is that big ball that sits on the opposite end of the arm attached to the fill valve. You can turn the screw that holds the float arm to the fill valve (a quarter turn at a time) to adjust the height of the float. This usually solves the problem of a running toilet. (If it’s caused by the water level or the ball sitting too high.)
Replace the fill valve.
This is another job that involves an expert — not just for replacing the assembly but for diagnosing the problem in the first place. Call Simpson with any questions!
