How to Replace a Toilet Cistern

A toilet cistern holds the water necessary to flush a toilet. The three most common cistern models in Australia are Bottom Inlet, Back Entry and Concealed. When your cistern springs a leak, it will almost certainly need replacing. And it may surprise you that it is not a particularly complicated or time-consuming job.

What cistern do I buy?

The first thing to do is to select a replacement cistern.  You can easily replace a broken cistern with a brand new one. Toilet cisterns come in a range of designs and brands. You’ll need to decide whether you want a back to wall inwall cistern, link (connector) toilet cistern, mid/low-level toilet cistern, concealed cistern, wall hung under-counter or a close coupled toilet cistern.

Brands like Caroma, Posh, Hideaway and Geberit all provide great options. It is also worth considering a concealed cistern. They provide an alternative to the contemporary cistern design by using space-saving solutions. They sit behind the wall, providing more usable space in your bathroom and an aesthetically better-looking toilet. The great thing about concealed cisterns is that they are relatively maintenance-free, so there is no need to fear about having your wall ripped apart when you encounter a problem. If you are unsure about which cistern might be best for your toilet, you can contact our team of local plumbers. We provide cistern installation services.

How do I remove an old toilet cistern?

The first step is to turn off the tap to the cistern. Then unscrew the water inlet pipe located at the bottom of your cistern. Once this is completed, you can remove the nuts and bolts that are used to attach the cistern to the toilet bowl. Once all the nuts, bolts and washers have been removed the cistern itself should simply lift off the toilet bowl.

How do I install a new toilet cistern?

Now that your old cistern has been removed, you will have a good idea of how your new one should be installed. It is important to make sure that it lines up correctly and the water inlet hose has been reattached properly. You can use plumbers tape to wrap up the inlet of the new cistern. Once you are sure that everything lines up and all connections have been reattached successfully, you can turn your water supply back on. Be sure to check the new cistern for leaks before continuing.
