3 Causes Of Slow-Moving Toilets

If you have one or more toilets in your home that are flushing very slowly, you should look into this issue. There might be a major problem with the plumbing in your home that needs to be addressed in order to avoid other problems. Here are three common reasons that toilets flush slowly.


The main thing you should be concerned about is a clog somewhere in your line. If a drain line is clogged, even partially, it can cause the toilets to flush slowly. This occurs because there is less space for the water to exit your home, and eventually, this could turn into a complete clog. If a line is clogged completely, nothing will be able to pass by it, and this will lead to wastewater coming up out of your toilets, sinks, and tub drains.

You could test your toilet to determine if there is a clog by pouring five gallons of water down the toilet very quickly. If the water goes down fast, there is most likely no clog anywhere in the line. If the water does not go down quickly, call a plumber to locate and fix the clogged line.

Blocked sewer vent

All the toilets and plumbing fixtures in your home should be tied to a sewer vent. This vent allows the sewer gases to leave your home through the vent in your roof. Unfortunately, this vent can get clogged; and when this happens, it reduces the air flow your toilet needs. When you flush your toilet, air is needed to make the water go down and to allow the fresh water to enter in. When there is a reduction in air flow, it will often cause a toilet to flush very sluggishly.

You can check out your sewer vent by going on your roof. This can be dangerous, though, so you may want to let a plumber do this if you do not feel qualified to walk on your roof.

Hard water

Over time, hard water can also cause toilets to flush slowly. Hard water contains sediments, which can get trapped in the pipes. This can restrict water flow to the toilet, and this may require two steps to fix it. The first step is getting a water treatment device to clean your water, and the second step may involve replacing some old plumbing pipes in your home.
