Does a toilet need a refill tube?
Without a properly functioning refill tube, the toilet bowl will either have no water, or overflow with too much water. The refill tube comes upwards in an arch from the fill valve, and then drains down directly into the flapper, which releases the clean water into the bowl.
Where does the refill tube go in a toilet tank?
The Refill Tube must be located above the Overflow Tube. If it’s pushed down into the Overflow Tube, it can siphon water from the tank into the bowl causing the Fill Valve to cycle on and off.
What is the purpose of the refill tube?
That tube provides water to refill the bowl. Without it, you’d only refill the tank. During the flush, the siphoning action through the trap pulls more water out of the bowl than is necessary to maintain a water seal, the water is replenished by the bowl refill.
What is a toilet fill valve tube?
The fill valve is the part of the toilet that is responsible for refilling the tank after being flushed. Over time, a worn or out of alignment fill valve can become a problem, cause a leak, and wear on valve’s components and parts.
Do all toilets have overflow pipe?
A modern toilet will have an internal overflow Flush Valve fitted, which is great as it removes the unsightly overflow pipe and saves drilling a hole in your house for it. But it does mean you need to look out for the signs that your cistern is overfilling.
Why does my fill valve keeps running?
Adjust the Fill Height by Checking the Float The water level in the tank is controlled by an adjustable float. A float that’s set too low produces a weak flush; if it’s set too high, water spills into the toilet overflow tube and the fill valve won’t shut off. The toilet keeps running.
Are toilet valves universal?
There are many types of fill valves available, and dozens if not hundreds of manufacturers who make them. Most are quite interchangeable and can fit the standard tank openings on any toilet, but do pay attention to sizes, especially the length of the valve stem.
Why does my toilet not have an overflow pipe?
The reason you do not have an overflow is that some “handyman” removed it and glued that Fluidmaster “repair flapper” over the hole in the tank. That device was supposed to be glued onto the old flush valve to replace a “bad” flapper device, not replace the entire flush valve.
Do I need an overflow pipe?
Overflow pipes are “warning pipes” It’s always important to get an overflow problem dealt with quickly because usually the pipe work and fittings connected to the overflow pipe have never been tested for leaks and, in many cases, the water can leak inside the property without you knowing.
What to do if your toilet refill tube is not working?
If the water does not flow through the nipple, the issue is with the fill valve and the valve requires replacement. Turn off the water supply. Unhook the opposite end of the refill tube from the top of the overflow tube, if water is flowing through the fill valve nipple.
How does the refill valve in a toilet work?
How Toilets Work. The filler valve (or refill valve) sends water in two directions, as shown in this figure: Some of the water goes down the refill tube and starts refilling the tank. The rest goes through the bowl refill tube, and down the overflow tube into the bowl. This refills the bowl slowly.
Why does the refill tube go into the overflow tube?
It prevents the tank from overflowing, by directing extra water to the bowl. Nothing prevents the bowl from overflowing, other than the fact that once the water level reaches a certain height the toilet flushes. The refill tube goes into the overflow tube and that water fills the bowl after each flush. Click to see full answer.
What kind of fill valve do I need for my toilet?
Initially used for low flow toilets in the nineties, they are not always reliable valves for modern toilets. Usually made of plastic, the floating cup type of fill valve is controlled by a floating cup attached to the fill valve shaft by a metal spring and actuating rod.
