I purchased a Fresca FTL2336 Apus One-Piece toilet and installed it. I can hear a constant drip of water escaping from the tank causing the toilet to refill every few hours. I have lifted the flapper, tightened the two screws holding down the bottom seal but problem persists. Any suggestions?

There will never be a dripping sound from the bowl unless there is water on the floor indicating a cracked bowl or a gasket has lived its life and needs replacing . The flush kit could drip though, Most likely an indication to adjust the level of the float or perhaps even replace the kit altogether, Never hearing the tank fill up is not related to dripping.

ok then go buy one from Lowes or Home Depot.

if the fluidmaster,itself is leaking, there is a rubber disk in the base of fluidmaster, replace disk. however, i can almost promise you the dripping you hear is from a bad flapper. replace with KORKY brand flapper. buy the basic black one, with no water saving gadgets on it.you will see cheaper black ones, but get the KORKY

either the fill valve is running and water is draining into the bowl via the overflow tube in the tank or the flapper is bad (or foreign matter) and it is allowing water to escape into the bowl through the flush valve slowly...causing the tank to drain and the fill valve to run every few minutes or so. start by inspecting/cleaning or replacing the flapper and hopefully that will do it because a one piece toilet flush valve needs a special wrench,to remove it, that you use with a ratchet. If you buy a new flush valve, it comes with the wrench (glorified piece of plastic) and is not too difficult to get the flush valve out. you can get a replacement at http://www.plumbingpartsdepot.com/ They do mail order, too. All you need is the toilet type - a four digit number embossed in the tank starting with a 2. hope this helps but if you need anything else just ask:)

There are only a coulple of places that the toilet could leak or, overflow and give you this problem. When you replaced the flapper valve, did it have an extra piece of rugger on it? Universal flappers have a round piece on them that are designed to fit over the overflow tube. If you flapper had this piece and you don't have need for it, you need to cut that out, if the flapper "hooks" to the overflow assembly. Leaving that piec on can contort the shape of the flapper and make it so it won't seal. If you are noticing constant movement(slight swirl) in the bowl, make sure the back tank is not constantly overflowing into overflow tube. If this is the case, your water level is too high. You will either need to adjust the water level and/or replace the fill valve. If you can hear the toilet running or leaking, push down on the flapper, if it stops, you have a problem with the flapper and/or the chain adjustment. When you install the flapper, you have ton make sure the chain is long enough to let the flapper fall and seal but, not so long that it can tangle or get between the the flapper and it's seal below it.

Basically, if water is flowing out of the overflow tube, then water must be coming in...I would suggest that you check the intake valve, it is probably not shutting off completely when the float comes up to the prescribed level,and continues to leak some water into the tank. That is what the overflow tube is there for.

Check flapper out and adjust water level in tank to proper level. If you get level right and it still does drip it sounds like the flapper is not sealing correctly to shut off water.

Toilet flappers are not to expensive and you can touch it with your hand and if you get a black residue off on your hands that a sign it needs replacing.

WHAT IS DRIPPING,?THE TANK ?OR IS STILL FILLING UP ?IT SOUNDS LIKE YOU NEED TO ADJUST THE WATER LEVEL TO THE PROPER 1.6 GALLONS PER FLUSH,WHICH IS MARKED ON THE INSIDE OF YOUR TANK SOMEWHERE,CAUSE WHAT YOUR HEARING IS THE WATER RUNNING DOWN THE OVERFLOW TUBE

Place a few drops of food coloring in the tank of the toilet, if it is leaking you will see the color seep into the toilet bowl within a short period of time. If you see the food color in the toilet bowl you will need to replace the flapper.

get a new filler assembly. the water in the tank is heavy enough to close the seal completely. or the rubber seal is not making contact. thats' why the leak.
change the whole assemble ususally correct the problem.
adjuste the flow to about 1/4 to 1/3 under the over flow. if that still don't give you the pressure. you ca adjust the flow tube to 1/5 under the cover. that is the max.
