The Homebuyers Plumbing Checklist

18 January

An informed buyer will check out the specs when buying a computer. When they’re purchasing a car, the exterior and interior aren’t the only ones that matter. They’ll check out what’s under the hood, too. It isn’t any different for homebuyers. Buying a house is a significant investment. Although people would say a home is an asset, it can turn into a liability once you incur expenses through its maintenance and upkeep.

If you want to get your money’s worth, check out the house’s features, especially its plumbing system. It’s better to know now for possible water damage and other plumbing issues. After all, plumbing is one of the costly systems to install, repair, and maintain in your home.

Don’t run into unexpected plumbing problems when buying a new home. Check out this handy plumbing checklist infographic below created by expert plumbers from the Gold Coast Plumbing Company.

For most people, buying a house will be the biggest purchase they will ever make. It’s stressful and is easy to miss some important things when inspecting, what could be, your new home. That last thing you need is unexpected plumbing expenses to make the enjoyment of buying a new home come crashing down.


While the exact number varies from area to area and season to season, the average daily water usage is around 340 litres per person or 900 litres per household.
MORE THAN 25% of the average daily water used comes from flushing the toilet
AROUND 14% is caused by leaking pipes


A lot of the time, even someone with no plumbing experience can identify potential problems with a home plumbing system. You need to know what to look for.


Flush every toilet in the house. While it is flushing, ensure that it drains properly and has no visible leakage. If you have the opportunity, you can also remove the top of the cistern to see whether the inner working appears in good condition.

Find the home hot water system and look it over for signs of corrosion. Using the outlet on the side, run some water and ensure that hot water comes out. If possible, ask the house’s current owner when the hot water system was last serviced.

Run all showers to ensure that they have adequate water pressure. Low pressure can be a good indicator of a more significant issue, such as an unseen leak or clog. While you are there, ensure that all water drains freely and that no water is leaking from the fixtures.

It’s not a pleasant job, but it is essential to get underneath the house to check for signs of leaks or water damage. Since most of a house’s plumbing is located underneath the house, doing this will allow you to catch any plumbing issues that you might have missed in your initial inspections.


Size does matter! OK, maybe not length, but definitely girth. Check that your prospective new home has pipes of the correct size installed. If the pipes are too small, the water pressure will be lower and could increase the potential for damage in the future. In most cases, you will want the pipes to be 3/4” from the water source to the home and 1/2” or larger from sinks and taps.


Check for obvious signs of overflowing water at overflow relief gullies, surcharging or gurgling and smells from the drains, which would indicate a potential blockage or problem with drain pipes.
