Low water pressure – I need help!

Plumbing Blackburn South

We received a call from a customer in Blackburn South, who reported low water pressure and no hot water to their household. The Doherty Plumbing Solutions office dispatched Tim and Kallista from our team to attend the property.

After investigating, they found that the main water line had been damaged due to garage construction works, leading to loss of pressure to the water flow.

Our crew got down to work, replacing the damaged section of the water pipe.

Great work team.

Plumbing Vermont South

A customer from Vermont South contacted the Doherty Plumbing Solutions office after they had begun experiencing low water pressure in the bathroom with water flow reducing to a slow dribble.

Our plumbing professional was at the scene promptly to assess the issue. It was found that the duo valve was faulty, and the fitting connected to the hot water unit was incorrectly aligned. These were subsequently disrupting the hot water flow.

After isolating the water supply to the water heater, our plumber replaced the duo valve and removed the existing tempering valve. The fitting was reworked to sort out the alignment and water pressure was tested. Everything was back to operating as it should.

Fantastic problem-solving skills, Tim!

What are the signs of low water pressure?

Inconsistent hot- and cold-water flow at your property can be very frustrating – whether you are a homeowner or have a commercial property. Some tell-tale signs can indicate the presence of low water pressure, as the case studies above highlight.

The biggest giveaway of poor water pressure is plumbing fixtures at your home or workplace not yielding enough water when taps are turned on in the kitchen or bathroom.

Dribbling showerheads are also indicators of low pressure in the property’s water flow.

Washing machines and dishwashers not working to their optimum capacity and taking longer to complete the cleaning cycles could potentially be due to weak water pressure.

Check the water pressure meter at your property. Australian standards stipulate ideal household water pressure at 500 kPa (kilo Pascal). Any reading below that will show signs of low water pressure.

What causes poor water pressure?

Reasons for low water pressure at home or office :

# Faulty valves – An underlying fault in the valve system of the property’s plumbing system (such as shutoff valve, water meter valve, etc.) can disrupt the water flow, causing reduction in water pressure.

# Faulty pressure regulator – These regulators help keep the water pressure levels balanced, such that high water pressure does not damage the plumbing connections. If these are not operating optimally, it could cause low or high water pressure.

# Pipe blockage – Organic debris or solid waste clogging the pipeline system could adversely affect water flow, and in turn, its pressure. Sediment build-up inside the pipeline narrows the diameter reducing water flow.

# Pipeline construction – If the pipeline construction at your property is not properly laid out, it prevents water from moving freely through the pipes. This could alter the water pressure, due to a blockage.

# Leaking plumbing fixtures – If a pipe develops a leak due to corrosion and damage, it also alters the water pressure and leads to loss of our precious resource.

    James was professional and knowledgeable. He explained my shower leaking issues as I was not able to attend myself. The plumbing work was completed promptly. And I was advised next steps with Tiler to make water proof. Very helpful and would definitely recommend to my family & friends.

    I had a great experience with the team at DP when they promptly addressed my hot water piping issue. George worked efficiently, and he was friendly and professional throughout the visit. He did a thorough job and took the time to ensure everything was done correctly. I would definitely recommend their services and would not hesitate to call them again.
