Toilet problems are particularly annoying because these household appliances are expected to work always, just as we expect water to pour from our faucets when we turn a valve, and sprinklers to go on when the timer clicks over. Fortunately, many toilet problems are an easy fix, including when a toilet takes forever to refill after a flush.
Here are the four primary reasons why your toilet isn’t working as it should.
Water Supply Valve Problem
You know that valve close to the wall under the tank, the one that looks like it can be turned like a faucet? That’s the water supply valve. If it’s not fully open then you’re only getting a trickle of water into your toilet after a flush. A trickle means a longer fill time, so make sure that valve is turned all the way on.
Your Float Is Waterlogged
Over time, a float can develop cracks and take in water. Weighed down, it’s going to float lower in the tank, which may cause the tank to fill incompletely or take a longer time to fill. A handy DIY-er will have no problem replacing the float assembly.
Valve Tube Problems
Inside the tank, the valve tube part of the water control assembly can, over time, become encrusted with calcium deposits, silt, and rust. This will impede the speed by which water can refill the tank. Pushing down on the float arm for a moment, so the bulb goes underwater, and then letting it rise again, produces a “pumping” flush through the valve tube that may, with multiple energetic pushes, loosen some of the debris.
Bold do-it-yourselfers may want to lift the hardware away from the tube to clean it out with a brush. Alternatively, and particularly if the toilet and its parts are old and failing, you may want to replace the control assembly completely.
Water Pressure Issues
An unlikely and less common issue is that of household water pressure. If the water supply valve is fully open and a slow fill of this toilet has been a chronic problem, consider discussing a water pressure booster with your trusted plumber.
