Understanding the problems and how to fix a leaking toilet
There are many causes why your toilet may not be functioning correctly which can be broken down into 3 categories.
If your toilet is constantly filling with water and the water is constantly spilling into the bowl via the built in overflow in the cistern, then the inlet valve has failed and will need replacing. Most of these inlet valve parts we carry in stock and can be replaced on the spot to fix your leaking toilet.
If your toilet is making a hissing noise or filling up the cistern irregularly through the night, what you will find is the outlet valve washer has split, is worn or perished and need replacing. Prime Plumbing stock a range of different types of outlet washers and can usually repair your cistern and get it functioning correctly again. If the cistern is still passing water into the bowl once the outlet washer has been replaced it could be the outlet flushing mechanism has warped and not sealing correctly or part of the mechanism is broken. At this point depending on the age and condition of the toilet suite it may be time to replace the cistern or the complete toilet suite.
If your toilet is leaking on the floor, depending on the toilet suite it could be one of the following issues
Replacing a toilet cistern or toilet suite
With purchasing a new cistern or toilet suite it’s true to say” you get what you pay for”. Many plumbers and home owners will go to the local hardware or plumbing store and purchase a cheap replacement cistern as the cheapest option to get their toilet back up and running. We have attended many of these jobs to fix there leaking toilets 12 months after they have had the cistern installed. As they are very low quality products we usually end up replacing the inlet valve which has failed in this short period of time. As spare parts for the outlet valve assembly in the plastic cistern are not readily available, we generally end up replacing the cistern with a quality and serviceable product.
Not all cisterns are the same
If you’re replacing a cistern on a 1970’s home or earlier, you will find an old style toilet. These toilets when manufactured were 12 litre single flush systems. Not because the manufacturer thought let’s make a product which uses a lot of water, It’s because the toilet bowl was manufactured in a way where it needed a large volume of water to flush away the waste. A lot of the new cisterns on the market are 4.5L full flush and 3L half flush products.
If you install one of these 4.5L/3L cisterns on a 12L bowl it’s only receiving just over a 3rd of the water volume required to flush the waste away.
I cannot recommend enough when replacing your cistern to have a Caroma Uniset II installed as they have a fully adjustable outlet mechanism which can be set to the either 4.5L/3L flush, 6L/3L flush or 9/4.5L flush to suit and flush properly on most types of bowls. Granted these cisterns are quite large and bulky, but if you decide to choose a different slimline product instead be ready to get the paint brush out and repaint the wall as most of the time the wall behind the cistern was never painted of the rooms paint colour has changed
Our plumbing team will check the following items to find the most compatible product for your installation, but if you want to choose a new toilet suite yourself you will need to consider the following factors
