Tip & How-To about Plumbing

How to check and see if your toilet flush valve is leaking.

We've all heard the mysterious sound of the toilet filling when no one has been in there for a while. Well the most common cause of this is a worn out flapper. An easy way to check this is to put a couple of drops of food coloring in your tank and wait five or ten minutes and see if any color appears in the bowl. If it does, then odds are you need to replace your flapper. I hope this has helped.

When I flush the toilet, water fills the bowl. After about 30 minutes, the water drains from the bowl completely.


Attached to the Flushvalve is a rubber stopper commonly called a flapper. If the flapper is worn this would cause the problem. Also sometimes the chain that attaches the flapper to the handle gets caught and the flapper sdoes not seat right. Check this, if it is clear and not obstructed try repalcing the flapper.

American Standard Elongated toilet bowl water level slowly drops


The tank holding the proper amount of water is a good sign. The inside of the stool is like the GOOSE NECK under you sink. It always holds water. This may sound like a bit of a hassle to do but if all 3 toilets are identical, here is what you can try if you are a bit handy. Go to the hardware store and purchase 4 toilet wax rings with a plastic flange and a few sets of toilet floor flange bolts(they are cheap and you can always return if not used, as It is better to have xtra parts on hand). Turn off the water supply to the "Mystery Toilet". Leave the tank and everything connected to the stool. Flush the toilet and remove all excess water from the tank and bowl. This can be done with a shop vac, sponge or towel. Disconnect the water supply to the tank. Remove the bolts holding the stool to the floor and carefully remove toilet. Scrap off all the old wax from the floor flange and bottom of stool. Now go and repeat this proceedure to one of the toilets that is working properly. In other words Switch the "Mystery Toilet" with a "Working Toilet" and see how they react. If the working toilet does it in the same bathroom and the "Mystery Toilet" does not do it in the other bathroom then you probably have a VENTING PROBLEM. If the "Mysery Toilet" Does it in the other bathroom then you most likely have a Defective Toilet. This Job is best done by 2 people, as it can sometimes be challenging to center the new wax ring on the toilet flange. Reconnect to the floor and reconnect water supply to the tanks. DO NOT OVERTIGHTEN BOLTS to the floor flange as you may crack the toilet. All drain lines must be vented properly for water to flow. If you are curious check out drain venting on the internet. Also, sometimes a vent can become obstructed with debris, ice, bird nest, etc.. I would 1st check the vent on the roof visually and then have someone flush and listen. If you believe the vent is clear....Then do the toilet switch and go from there.....Hope this helps and Happy Holidays....Joe
