What to Do When Your Toilet Tank Cracks?

Your toilet consists of two parts which are the tank and the bowl. Old age, sudden change in temperature, or strong impacts on the toilet tank can cause it to crack.

If it is more than a hairline crack, you’ll find a pool of mysterious water flooding your toilet floor.

Can a cracked toilet tank be repaired? Yes, to an extent, you can fix a cracked toilet tank; however, there is a chance that the tank might be badly damaged and need to be replaced altogether.

Firstly, to repair a cracked toilet tank, you must investigate the outside of a tank. If you see a hairline crack, you do not have to worry much. However, if the hairline crack is not attended to, it might become more prominent and cause future problems.

If you cannot locate a crack on the outside of the tank, look inside. To have a look inside, you have to empty the tank first. You can do it by closing the toilet tap and flushing until all the water is gone from the tank.

After that, you can spot the crack, and if the gap lies below the waterline, it can be fixed with epoxy or other porcelain sealants.

A minor or a major impact on your tank can cause it to leak. Whichever the cause, you should not delay repairing the cracked toilet tank, especially when it is leaking, avoiding any future hassle.

Step 1: Cut off the Water Supply

You should always turn off the water supply after you have spotted a crack, regardless of whether it is leaking or not.

Step 2: Wipe the Tank

In doing so,you ensure a successful sealant application; otherwise, the sealant may not stick, and all your hard work will go to waste. Make sure that the inside, as well as the outside of the tank, is dry.

Step 3: Cover the Crack

After wiping inside and outside the tank, apply a porcelain sealant over the crack to repair the cracked toilet tank. A silicone epoxy sealant works best. You can easily find it in nearby mechanic shops.

While shopping for the sealant, look for a caulking gun too. Although not a necessity, a caulking gun is a precision tool that can be filled with a sealant, and using it reduces waste and gives a precise application.

Step 4: Smooth It out

Once you have applied the sealant, smooth it down with a putty knife or a knife you no longer use. Spreading the sealant over the surface will eliminate the chalky look, and covering more areas around the crack will ensure the damage is efficiently covered.

Step 5: Let It Dry

After you have applied the sealant, let it dry for 24 hours. Meanwhile, use another toilet because using it before the adhesivedries will hamper the integrity of your work.

As a result, you might have to revisit and apply the sealant again or, worst-case scenario, replace the tank if the crack deepens. So, be patient and let the adhesive dry.

Step 6: Let the Tank Refill

Once the sealant is dry, you can turn on the toilet’s valve and let the water fill your tank. If the leak persists, you have to drain the water again and see if you have missed a crack. If there is no leak, you are good to use the toilet again.
