Best Toilet Flush Valve Buying Guide
Toilet owners have to deal with three major problems: leaky valves, noisy filling, and a weak flush. Each can lead to even more problems.
While an upgrade can provide a simple solution, there are far better versions you can find out there. But you need a good criterion to know which one to choose. The following are the most important ones:
Choose a material that withstands the test of time. Go for superior ABS and rubber materials, which provide higher resistance to corrosion. It’s crucial, especially for high-end, small investment toilets.
The higher the refill rate, the less time you’ll have to wait. Consider additional water-saving features to reduce energy bills. For instance, a leak detection system or adjustable water volume.
Choose a quiet water filling system. Most of the latest models operate quietly. After all, you don’t want everyone to know someone is using the toilet, do you?
A flush valve can’t fit all toilets. For instance, most models aren’t compatible with old toilets. Ensure to check the dimensions and height. An adjustable height will be a huge advantage.
An inferior seal makes a weak flushing pressure. Choose a flapper or valve with a tight seal. It will reduce water wastage.
Tips: How To Change Toilet Flush Valve
A toilet flush valve will have to malfunction at one point, and you don’t want to be caught unawares when the time comes. So, what are tips for replacing a toilet flush valve?
Step 1: Prepare for Installation
Shut off the water inlet and thoroughly drain the tank. Use a sponge or vacuum to dry. Remove the tank if necessary.
Remove the thick rubber gasket and loosen the nut underneath. By doing so, the flush valve will be able to come right off. Clean the area on the sides to remove debris.
Step 2: Valve Replacement
Your new valve goes in just the same way the old one came out. Keep the thread side up and direct through the hole. Don’t tighten too much; otherwise, the tank might crack.
Adjust the height of the tube. In most cases, the manufacturer specifies the correct height. Make it at least one inch below the hole where the flush lever mounts.
Attach the rubber gasket and use the nut to screw it into position. Make it tight for a perfect seal. Replace the hose and reconnect flapper chain.
Step 3: Testing and Troubleshooting
Flush a few times to make sure there’s no leak. Use a flashlight to check for drips under the toilet. If any, tighten the connections.
