The hissing sound from the bathroom isn’t a rattlesnake, that’s your slow running toilet. The sound is mind-numbing and drowning out all other thoughts.

OK, it’s time for repairs.

The tricky part is the solution for fixing a slow running toilet really depends on what the problem is, and where it is. Clearing a toilet blockage is a completely different task to replacing the fill valve.

Therefore, you have to know where the offending fault is so you can best fix it. To do that, well you have to investigate. Arguably the most direct way to do that is to work your way down from the toilet tank through to the bowl. Let’s have a look.

The Toilet Tank

Starting at the very top, lift the lid on your tank.

Take a look at how high or low the water level is. If the fill level is too low, there may not be enough force behind the flush. That’s why you have a weaker flush and a slower, more annoying fill.

Here are some of the most likely offenders for a low water level in the tank.

Toilet float

Also known as a ballcock or float valve, the toilet float is a round, plastic object attached to the fill valve. It dictates the fill level, and if it’s damaged or bent downwards, the tank will not fill high enough. Or if it’s bent up, the water level will rise too high and could overflow.

Fill tube

The fill tube, refill tube or filler tube, is where the water enters the tank from the supply line. A blockage or damage to the tube would impact water flow and potentially how much water enters.

Fill valve

Essentially, the fill valve is the entire component which draws water into the tank and through to the fill tube and overflow tube. It forms the bulk of the tank and will cause issues if blocked.

Meanwhile, the flush valve and flappers could also be to blame. This is where the water exits your toilet tank and flows through to the bowl. The seal should be strong and tight. But if it’s aged or worn, you’ll have a hissing toilet that fills slowly.

Thankfully for each part there is a simple fix: replacement. Skip the patch up job by bending a toilet float back in place and just pop down to the hardware store for a replacement part.

toil2-1 Tricks for Fixing a Slow Running Toilet

The Toilet Bowl

Think of your time in college. Just like you did, a toilet works best under pressure. Without it, then your water will just slowly drain and leave behind plenty of solids that you want gone.

If the toilet bowl itself is damaged, whether it has a crack, there’s not necessarily a lot you can do. That is a job for the professionals, so you’ll definitely want to look for a company like Book a Plumber Online for immediate assistance.

However, you do have some other quality solutions depending on the issue!

Sediment Build Up

Even though we all do our best to stay on top of maintaining a clean toilet, when the toilet is running slowly have you ever looked under the rim?

Sediment and solids residue can build up underneath the rim following a flush, and that can block your inner jets. This is where the water comes out to provide an all-round flush. But if the blockage worsens then the pressure will weaken. So grab a brush, scrub hard, and make sure to keep those jets clear!

Clogged Toilet

A clog or blockage could be the most serious reason for a slow running toilet. Depending on the cause, the solution will vary.

Simple blockages like toilet paper can be cleared easily enough with a plunger and homemade or store bought drain cleaner. A shallow blockage will be gone in no time!

However, if you have a stubborn collection of wet wipes or perhaps some toys the kids have flushed down, a plunger might not help as much. Sure, it could alleviate the issue for a short while, but it’s likely to return. Likewise, a tree root invasion or damaged pipes need more specialised attention. So if it seems like your plunging has not helped a slow running toilet, call in a local plumber.

Damaged Toilet Bowl

Finally, if you haven’t managed to find a solution to fix a running toilet from the list above, it may be a damaged toilet bowl. Or your old toilet might just have to be replaced completely! That way you can avoid a leaky toilet and the headache of a slowly filling bowl.

Again, unfortunately this isn’t really a simple task to do yourself unless you have some advanced DIY skills. But with a quick internet search you can find a local expert and book a plumber for your toilet repairs.
