The Homebuyers Plumbing Checklist

18 January

An informed buyer will check out the specs when buying a computer. When 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. Future property owners should check the plumbing system of their eyed property. Buying a house is a significant investment, and it’s only wise to have a household plumbing inspection checklist before buying into a major plumbing system failure. Although people would say a home is an asset, it can become a liability once you incur expenses through its maintenance and upkeep. And especially if there’s a plumbing problem you weren’t aware of. Can you imagine low water pressure, clogged p trap and water drains, a gurgling sound in the bathtub, the water heater producing only cold water supply, either gas water heaters or electric, water dripping in the garden tap, and water leaks somewhere in the house no one knows the exact correct location? And these are just some of the issues you can face with your plumbing systems. You can encounter far worse problems and not be able to inspect like in your sewer system visually.

If you want to get your money’s worth, check out the house’s features, especially its plumbing system— the sewer and drainage lines, the cold water inlet pipe in your water heater, the hot water exit pipe, and other plumbing fixtures.

Try to get as much information as you can about the sewer lines and water drainage systems; if it has an underfloor drainage system, if it’s a tank system, or if there’s a broken sewer pipe you should know about; ask too if the previous owner cleaned the kitchen sink drain regularly; check the vent pipes; learn more about the water supply and water pressure in the neighbourhood – perform a water piping pressure test; if appliances like the garbage disposal or water dispenser go with the house, check the washing machine and such; check the shutoff valves of the hot water system or water heater to see if it’s still working or are there only cold water available? Know if you’ll be dealing with some plumbing problems as soon as possible.

Knowing about possible water damage and other plumbing issues is better. Issues spotted early on can save you a lot of time and money. After all, plumbing is one of the most costly systems to install, repair, and maintain in your home. Take your time checking stuff; you have the right as potential buyers. Check the toilet base for signs of water leaks; see if the wax ring needs replacement; ensure the waste outlet is in its correct location; ask if there is pipe damage and if all pipe insulation is in place; are all the drains clear? These are some things you must keep in mind about the plumbing system to ensure you won’t be faced with a bigger problem once you’ve bought the house. Save time and money on your plumbing system in the best way possible with the right questions.

For most people, buying a house will be the biggest purchase they will ever make. It’s stressful, and it is easy to miss some essential things when inspecting what could be your new home. The 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


Often, 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 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. 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 indicate a more significant issue, such as an unseen leak or clog. While there, ensure that all water drains freely and no water leaks 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 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, indicating a potential blockage or problem with drain pipes.
