While all modern homes are designed with balanced plumbing systems, it is essential to be aware of the dangers of water pressure that is too high. High water pressure can lead to burst pipes and water damage, but it can also affect warranties on household appliances.

Even if you employ the most reliable plumbers in Melbourne, wear and tear can lead to leaks in the very best systems. Precision Electrical and Plumbing recommends that homeowners check their water pressure regularly.

You can usually identify high water pressure problems from leaks in plumbing pipework. For instance, you might hear dripping pipe water at night, or the water in your toilet system may run even when the toilet is not in use. If ignored, the situation will gradually get worse and worse.

Understanding High Water Pressure

Water pressure is the strength of water flow in your pipes, measured in kilopascals (kPa) or PSI (pounds per inch). This pressure – or force – determines the water flow you get out of your taps. If the pressure is too low, your tap, toilets, and shower will not work correctly.

Municipalities provide water for houses to meet the Australian Standards, and the pressure should be 500 kPa. But the water supply is considerably higher, usually between 800 and 1,000 kPa, so it can be used for fire hydrants, multi-storey buildings, and cluster housing where there is a high number of homes. Plumbers tap into the water mains via a communication pipe and install smaller diameter pipework to deliver water to domestic dwellings. This ensures your water pressure doesn’t rise above the mandated 500 kPa. But be warned that even when the pressure is set to standard, at night, it often increases because fewer people are using water in the area. This explains why leakages often happen overnight.

High water pressure can also be caused by thermal expansion when water is heated.

Steps to Take to Control High Water Pressure

The water pressure in your home must stay within the optimal operating range. Precision Electrical and Plumbing will install a valve at the water meter to control the pressure if it is too high. Pressure limiting valves will also ensure that the pressure from the municipal water supply is reduced in keeping with the standards. Ideally, a PLV should be positioned at the water meter to protect the entire supply line into the house and garden. The standards require valves that either limit or reduce pressure to be located where it is easy to get to the valve for maintenance or replace it if it wears out.

Qualified and registered plumbers in Melbourne will be familiar with the Standards requirements. They will also know that devices used to reduce pressure may not be buried underground and that they must be protected from any dangers of freezing in winter.

Remember when you look for plumbers in Melbourne to ensure that they are licensed according to the Plumbers Licensing and Plumbing Standards. Precision Electrical and Plumbing is licensed, and our team has regular training to ensure we all stay abreast of changing technology.
