Toilet Flush Valve Seal Replacement An awesome member of our community made this guide. It is not managed by iFixit staff. This guide is specific to a Flushmaster brand (Flushmaster, Inc.) toilet Flush Valve Seal that fits Mansfield(R) 210 & 211 Flush Valves. However, the shortcut method may also be applied to many other brands of toilet flush valves. This is a shortcut, time/labor-saving, method of installing a replacement "flush valve seal" to stop water inside the toilet tank from seeping/leaking down the drain (and the continuous, annoying sound that accompanies this water loss). Mansfield Toilet Flush Valve Seal American Standard Flush Valve Seal This is the New Valve Seal used in this guide, available at hardware stores and home centers. Using this New Seal installation shortcut method, it will NOT be necessary to do the following (of the original instructions that accompany the New Seal product): "Turn off water supply to toilet and drain tank" and "Unhook trip lever..."

[any "chain" will need to be momentarily unhooked.] and "Unthread stop cap..." and "Lift float assembly off....." Remove the top of the toilet tank. With a towel nearby, roll-up your sleeves. Flush the toilet to lower the tank water level. Immediately identify the old, worn [red] Valve Seal at bottom of the vertical assembly of Overflow Tube and Float. Reach into water tank and remove the worn valve seal by pulling it, like an old rubber band, with your finger tips (or pliers) until it breaks. Roll the new seal and stick it through the square trip lever holder and lasso the free end of the trip lever (the opposite end of the lever is attached to the flush lever outside of the tank). Keeping the trip lever through large center hole of the new seal, pull the new seal in the reverse direction back through the square trip lever holder. Turn the trip lever holder as you do this to allow more space to ease the new seal back through. When the new seal is between where the trip lever is connected to tank and where trip lever protrudes through square trip lever holder, for a moment, pull the flexible water refill tube out of the center of the stop cap.

Point the free end of it down, as water may still be coming through it after flushing. Take the new seal just over the stop cap and replace the water refill tube, being careful not to splash any water coming out of it.Hot Tub Jets Fall Out Gently stretch and pull the new seal all the way down the vertical assembly of the overflow tube and float near the bottom and position it into its top groove of the flush valve.Pink And White Striped Shower Curtain Once in place, you should be able to gently grasp the edge of the new seal and turn it in place in the groove, around the base of the flush valve. How To Change Fuse On Ac UnitCheck the seal by flushing, watching and listening. This is the reverse side of the Flush Valve Seal package.

Flush Valve Seals will need to be replaced, at least, once every few years, depending on water condition. Other kinds of toilet water tanks may have similar assemblies. Why call a plumber for something so easy to do yourself?!

If the leak is at the bolts: Make certain that there are no metal washers in the tank. This will cause a leak. Sometimes just resetting the position of the bolt head and rubber washer will seal that opening. Tighten down the tank to the bowl so that the tank sits on the ridge of the bowl. On most toilets the porcelain tank rests on the porcelain ridge of the bowl. The needed pressure on the bolt head and washer will seal the tank. Some bowls will not have a ridge, but use rubber washers or inserts to support the tank. Tighten down the tank until the rubber washers or inserts are compressed. Then check for leaks again. Note: The nut and metal washer used between the tank and bowl help to hold the bolt straight while you install the tank onto the bowl.

Before you install the tank use the nut and washer under the tank to seal. Place the tank on the sink. Add water and watch for leaks. This is an easier way to troubleshoot potential leak problems before putting the tank onto the bowl. Caution: Some toilets will not allow the nut and metal washer between the tank and bowl because the space is too narrow. If the hex nut rests on the porcelain, it can crack the bowl. In this case remove the hex nut and washer. Use your best judgment when using these parts. If there is constant leaking between the tank and bowl, there may be a crack in the porcelain or the flush valve plastic housing. A constant leak means the lock nut is not tight enough or the rubber washer inside the tank has flashing (excess rubber) or fissure-like cracks. Using a pipe wrench; tighten the lock nut 1/4 turn more, dry and then check for leaking. If the leaking reduces then go 1/4 turn more and check again. If this still does not seal it then do not tighten anymore.

Check the parts and gasket for any signs of flashing (excess rubber), or cracks, etc. If you find flashing, use your fingers to pull it off or use a razor blade to carefully cut away any loose rubber. Make sure you do not cut into the washer. If the leaking gets worse when you tighten the lock nut, something is cracked. If it only leaks when you flush the tank, the problem is at the sponge/rubber gasket. Leaking may be caused by a tank that is not tightened enough. The tank should rest on the ridge of the bowl for stability -- sealing the tank to the bowl with the sponge/rubber gasket. If you have already tightened the tank down to the bowl STOP! DO NOT TIGHTEN THE BOLTS ANYMORE! Check the fit of the gasket on the flush valve and on the bowl. The sponge/rubber gasket may not be a compatible type for your toilet. Compare this gasket in relative shape and size to the gasket you took out. If they are similar (or the same) proceed further. If not, you may need to purchase the correct gasket to finish the job.

If there is leaking at the lock nut of the fill valve: The washer in the tank may not be positioned correctly. The flat surface of the shank washer should be facing up and set against the flanged section of the fill valve. The lock nut is too loose: Turn the lock nut ¼ turn more. Dry and check for leaking. If this reduces the leak then go ¼ turn more, dry and check for leaking. Try using a little dab of silicone sealant under the shank washer inside the tank. Sometimes the hole has a chip or is out of round. The threaded shank is cracked. This would be confirmed by the fact that each time you tighten the lock nut the leak gets worse. Even if you install a new shank washer it will still leak. In this case replace the fill valve. Leak at the coupling nut: Is the coupling nut touching the lock nut? If yes, the tank may be thicker than most. There are two immediate solutions without replacing the water supply or the fill valve. Use a flat file on the top of the coupling nut.

File 1/8” off of the nut. If the coupling nut is not a part of a stainless steel or vinyl connector, you can place one or two stainless steel metal washers under the cone washer and then install. When you are using metal-flanged tubing as your water supply, you must ask yourself "Is this supply tubing new?" New tubing may only need a little more tightening. Used tubing should be replaced. There is a flat washer attached to the metal-flanged tubing that is used as a seal between the fill valve and flanged tubing. Because it keeps the impression of the previous fill valve, it may not match up to the new valve and ultimately leak. In this case, install a new spiral tubing washer or a completely new water supply line. If you hand tighten the coupling nut but your hand strength is not what it use to be, or the position of the toilet makes it difficult to get a good grip on the lock nut, use a wrench and turn the coupling nut ¼ turn beyond hand tightening. Dry it and check for leaking.
