How to Tell Your Toilet Has a Faulty Inlet/Fill Valve
The inlet or fill valve in your toilet cistern is the special mechanism that enables the water to flow freely into the tank. This ensures that your toilet will be able to flush next time you need to clear it. Over time though, these valves wear out and eventually when they breakdown you will have to hire an experienced person to repair the damage.
To help you spot when your toilet has a faulty inlet or fill valve, look out for the following three signs and deal with it as quickly as possible.
The Cistern (Water Tank) Takes Longer than Usual to Fill Up
If you find that after flushing, your toilet is taking an awfully long time to refill, this can be very frustrating. Moreover, it could be a sign that your fill valve is blocked, and water is having trouble flowing through it. Rather than rushing to buy a new one, check if there is an easy to remove blockage down there first. If you are still having trouble shifting the blockage and don’t feel confident dealing with it yourself, speak to a local and reputable handyman or plumber.
The Flushing is Weaker than Usual or Isn’t Working at All
When the flush for your toilet is either not working at all or is weaker than it usually is, even with the handle/button pressed all the way down, it could be that the cistern (water tank) in your toilet system is not being refilled properly. It could also mean that the float shut-off has been set far too low, so, if you’re confident about doing it, try bending your toilet’s float arm in an upwards direction to see if it is that or the fill valve causing the problem. In the end, if it’s not the float shut-off, it is probably likely that your fill valve is either blocked or damaged and not allowing any water to pass through it.
Toilet is Constantly Running
If you find that your toilet is constantly running, this is one of the most common signs that the fill valve is not working properly. However, it is not the only cause of a toilet that’s running constantly, so it’s best to rule out the other causes first, before taking any further action. Start by looking inside the water tank. If you see that water is constantly running over the fill valve and through the overflow hole, your float may not be set properly. If you have the type of float that is on a metal arm try to bend the float arm downwards to make sure the float triggers the water shut-off lower. If the toilet stops running constantly, then there’s nothing wrong with the fill valve.
However it maybe that you have a different type of float, and the most modern and usual type. If this is the case you cannot just bend a rod. You would need to make an adjustment on the inlet valve.
Generally speaking inlet valves have a rough lifespan of about 7yrs.
Using any kind of cleaning blocks on the cistern (water tank) will reduce this time considerably, and as such is not recommended.
Use cleaning products and blocks in the main toilet bowl only.
All in all if in doubt contact me for further advice.
It is recommended to have both the inlet valve and the flush vale replaced at the same time.
This not only avoids inconvenience of having to call me out again but it would be false economy.
