Toilet Tank Leaking from Bolts

Causes of toilet bottom leaks

A leaking toilet bottom can be continuous or just when you use the flush. In both cases, the reason is an imperfection in the internal components. The problem sources are,

Wax seal failure

A wax ring makes an airtight seal around the pipes and base of the toilet. Imperfection in the seal can induce the leakage of water when you use the flush. One should try to improve the wax seal once every three years to avoid bottom leakage.

Bolts attachment

Two tee-bolts hold the base of the toilet to the floor. When the bolts get loosened up, the wax seal breaks and causes bottom leakage. A wobbling toilet is to blame for most of the toilet seal damages.

Broken pipes

When you turn on the flush, a broken pipe will leak out water and in a continuous manner. This is often the case of too much pressure on the pipes, or someone pushed it by accident.

Clean the remaining water

Remember the sponge? Use it to suck all the remaining water from the floor and into the bucket. Clean the pipes, joints, and attachments.

Open everything up

Now, try removing the plastic cover from the tee bolts on either side of the toilet base. Open the bolts with a wrench and break off the seal.

Check for pipe breaks

Take a close look at the pipe joints. Sometimes too much pressure can damage the threads of the pipe, leading to water leaks. If there is any problem with the pipe joints, replace them.

Replace the wax ring

After that, you need to remove the remaining bits of wax from the attachment with a wax knife. Remember to clean everything off before attaching the new seal.

Carefully lift the toilet and place the new seal in place of the old one. Using your weight, press the seal and lock it in place.

Attach the tee bolt

If you are done with the step, now place the washer and nuts back on the tee bolts. Try using a new set of bolts for maximum efficiency. Tighten the nuts with a wrench and make sure everything is perfect. Too much pressure will just crack your porcelain.

Finally, turn the water supply, and you can use the toilet without any leaks while flushing.

Note: Sometimes, you need to replace the flappers too and make sure it is working correctly.
