A properly functioning toilet is essential for a comfortable and functional bathroom. However, if you’ve noticed that your toilet wobbles or leaks around the base, it could be due to a low toilet flange. The toilet flange is the piece that connects the toilet to the floor and the waste pipe. If it sits too low, it can cause various issues. In this blog, we will provide you with a step-by-step guide on how to raise a low toilet flange, ensuring a stable and leak-free toilet installation. By following these instructions, you can address the problem and restore the functionality of your bathroom plumbing.

  1. Assess the Situation: Before you start raising the toilet flange, it’s important to assess the situation and confirm that a low flange is indeed the issue. Check for any signs of movement or leaking around the toilet base. If the flange appears to be lower than the finished floor level or if there are gaps between the toilet and the floor, it’s likely that you have a low flange problem.
  2. Gather the Necessary Tools and Materials: To raise a low toilet flange, you’ll need a few tools and materials. These typically include a wax ring, flange extender kit, a hacksaw or reciprocating saw, PVC primer and cement, adjustable pliers, a putty knife, and a screwdriver. Having these items on hand will make the process smoother and more efficient.
  3. Remove the Toilet: To access and raise the flange, you’ll need to remove the toilet. Start by shutting off the water supply to the toilet and flushing it to empty the tank. Disconnect the water supply line and remove the nuts securing the toilet to the floor bolts. Carefully lift the toilet straight up and place it on a protective surface to prevent damage.
  4. Remove the Existing Flange: Inspect the existing flange and determine whether it needs to be completely replaced or can be raised using an extender kit. If the flange is damaged or in poor condition, it’s recommended to replace it entirely. Use a hacksaw or reciprocating saw to cut through the old flange and remove it from the drain pipe. Clean the area around the drain pipe to ensure a proper seal for the new flange.
  5. Install the Flange Extender or New Flange: Depending on the condition of the existing flange, you can either install a flange extender or a new flange. If using a flange extender, carefully place it on top of the existing flange and align it with the bolt holes. Secure the extender to the floor using the provided screws. If installing a new flange, follow the manufacturer’s instructions to position it correctly and secure it in place.
  6. Reinstall the Toilet: Once the flange is raised or replaced, it’s time to reinstall the toilet. Begin by placing a new wax ring on the flange or extender. Carefully lower the toilet onto the wax ring, aligning the bolt holes with the floor bolts. Gently press the toilet down to create a proper seal. Secure the toilet to the floor bolts using the nuts, but avoid over-tightening to prevent damage.
  7. Test for Leaks and Stability: Turn on the water supply and allow the tank to fill. Check for any leaks around the base of the toilet and ensure that it sits securely on the floor. Give the toilet a gentle shake to confirm its stability. If necessary, adjust the position or tighten the floor bolts to eliminate any movement.
