Toilet Plumbing

A flushing toilet is one of the simplest systems you will come across in your home. Although the mechanism may look very simple from the outside (source), the whole working happens inside the toilet tank. In most cases, any fault in the toilet can be solved on your own without the help of a professional plumber (in Edinburgh). DIYs work well when you have to solve a toilet-related issue. It only needs an expert help in case of a major issue that cannot be solved by inexperienced hands.

Your toilet includes a lot of parts which are generally not visible to you as they are all composed inside. These parts are (source) as follow;

  • Handle and flush rod
  • Lift chain
  • Flapper
  • Flush valve
  • Overflow tube
  • Supply tube
  • Shutoff valve
  • Water supply valve
  • Float cup
  • Refill tube
  • Toilet bowl
  • Wax ring

But if we had to narrow down to the only two main parts of the toilet; they’d be the fill valve and flush valve.

Let us now understand the plumbing problems around the toilets, why do they happen and how to solve them–

1. Leaks: A leak is a reason why the water in your toilet runs continuously even after the flushing is done. This is not only irritating and wastes a lot of water but can also strike up your water bill to another level.

If you notice the leak from the tank bowl or the toilet flush, the only way to repair it is to remove the tank from the bowl so that the parts at fault can be replaced. The parts which can be replaced to stop the leaks are the tank bolts, rubber washer, and gaskets on the flush valve.

If the leak is in the fill valve (source) that helps in refilling the tank after every flush, consider replacing it. A fill valve may be worn, tore or old which ultimately leads to a leakage. Using a few basic tools, you can do the replacement yourself.

2. No leak but the toilet is still running: In such a situation, consider lifting the toilet tank. When you don’t see any part leaking but the water is still running down the toilet, either the toilet flush valve or the fill valve is at fault.

You will come to know which valve is at fault by looking at the overflow tube. If the water is over-flowing into the tube and has crossed its top level, the problem is in the toilet fill valve; while the flush valve is at fault when the water level is below the top of the tube.

Easy ways to repair the fill valve on your own –

• Adjust the float arm by bending it
• Replace the washer
• If the valve still does not seem to get fixed, replace it

Easy ways to repair the flush valve on your own –

• Check for the worn out flapper and the chain. If there is too much slack on the chain, get rid of it.
• Replace the toilet flush handle if it is broken/corroded.
• If there is an issue in some other part that you cannot figure out, call out for an experienced plumber.

3. Clogged toilet: A clog in the toilet can be due to either waste, sanitary napkins, baby towels, etc. that goes down the toilet drain and gets stuck. This is one of the most general issues with toilet plumbing and is easy to fix yourself. Use the help of a plunger to get rid of the blockage, or use an enzyme product. You can also use a plumbing snake (source) if the plunger doesn’t help.
