How to Replace a Toilet Seal: Step-by-Step Guide
Posted by William Heinselman on
A leaky toilet seal can lead to water damage, unpleasant odors, and higher utility bills if left unchecked. Fortunately, replacing a toilet seal is a straightforward DIY project that Sacramento homeowners can tackle in just a few steps. Whether you're dealing with a worn-out wax ring or a newer rubber gasket, this step-by-step guide will walk you through the process, ensuring a secure and leak-free toilet. Plus, we’ll share some local tips on where to find the right replacement parts in Sacramento and when it’s best to call a professional plumber. Let’s get started!
What is a Toilet Seal?
As a toilet’s handle is triggered, the flush valve at the tank bottom will open and permit the water stored in the tank to enter the bowl. A seal is placed around the valve to prevent leaks. The toilet will continuously run if the valve or valve’s seal breaks or corrodes. That is when it is time to replace the seal.
Replacement of a toilet seal is an easy job that does not take much time. However, if you do not feel comfortable working with your toilet, it is always an option to call a plumber. Sacramento plumbing professionals, Express Sewer and Drain are equipped to handle any job, big or small.
How to Replace a Toilet Seal
To begin replacing your toilet seal, turn off the water supply. This is just below the tank, and it must be rotated clockwise to stop water from moving into the tank. To empty the tank completely, flush the toilet.
Remove the metal valve chain from the flush valve. Disconnect the water supply hose from underneath the tank. You can do this by turning its mounting nut in a counterclockwise direction using a wrench.
Using the same wrench, remove the bolts securing the tank to the toilet bowl. Next, lift the tank off of the toilet bowl. You should now see the flush valve’s spud nut and washer on the underside of the toilet tank. Detach the spud washer from the spud nut and remove the spud nut that secures the valve to the tank’s bottom. To do this, you will need a spud wrench. Utilizing the wrench, rotate the nut in a counterclockwise direction.
Raise the flush valve seal out of the toilet tank. Slip the new valve seal onto the bottom of the flush valve. Place the valve back into the toilet tank. The spud nut on the underside of the flush valve can be tightened by turning it in a clockwise direction. Apply a new spud washer on top of this spud nut.
The metal valve chain can now be reattached to the flush valve. Place the tank on top of the toilet bowl, and then, using your wrench, position the tank’s retaining bolts. The water supply hose can now be re-connected and the water valve turned back on. The toilet can be used after the tank is refilled with water.
Common Mistakes When Replacing a Toilet Seal and How to Avoid Them
When replacing a toilet seal, even a small mistake can lead to leaks, water damage, and the hassle of redoing the job. To ensure a successful installation, watch out for these common pitfalls and follow these tips to avoid them:
- Not fully removing the old seal – Any leftover wax or debris can prevent a tight seal. Scrape off the old wax ring completely and clean the surface before installing the new one.
- Misaligning the toilet – If the toilet isn’t placed squarely over the flange, the seal may not sit properly, leading to leaks. Lower the toilet carefully and ensure it aligns before pressing down.
- Overtightening the bolts – While securing the toilet is important, overtightening can crack the base. Tighten the bolts evenly and gradually until snug, avoiding excessive force.
- Choosing the wrong type of seal – Wax rings and rubber gaskets serve different needs. If your toilet sits on a tile or uneven floor, consider an extra-thick wax ring or a rubber seal for a better fit.
- Forgetting to check the flange – If the toilet flange is cracked or sits too low, even a new seal won’t fix the issue. Inspect the flange before replacing the seal and use a flange extender if needed.
By avoiding these mistakes, Sacramento homeowners can ensure a secure, long-lasting toilet seal replacement without unnecessary headaches.
