Low water pressure can come from a mix of things. Sometimes it is old pipework, sometimes a valve has worn out, and other times the issue is coming from the water supply outside your home. We look over the whole setup, find out what is causing the slow flow and explain the best fix in simple terms. All work is carried out to current BCP plumbing standards.

Weak pressure can show up slowly over time or happen all at once. Old galvanised pipes, blocked filters, worn-out flexi hoses, ageing mixer taps or tempering valves can all cause the water to slow down. Hot water units can also play up and restrict flow without warning. We start by looking at the most likely spots, rule things out one by one and figure out what is holding the water back.
We usually start outside at the metre to see what the pressure looks like there, then compare it to the pressure inside your home. If there is a big difference, something on the property is restricting the flow.
We check fittings, valves, flexi hoses, filters, shower heads and any pipework that may have built-up debris or corrosion. Once we find the trouble area, we let you know what is going on and what needs to be done to sort it out.
Fixing low water pressure can be simple or a bit more involved, depending on what we find. Sometimes it is a blocked aerator or a kinked hose. Other times a valve needs replacing or an older hot water unit needs attention.
Once we repair the problem, we test the flow again so you can see the improvement straight away.

Frequently Asked Questions
Usually, it’s blocked pipes, leaks somewhere in the system, or old, corroded plumbing that can no longer keep up. Sometimes the street supply’s having issues, or your pressure regulator’s stuffed with debris. Could be a few things, really.
We check your entire system – pipes, valves, regulators – and find what’s causing the uneven flow. There might be a need to clear blockages, fix leaks, or adjust your regulator. Once we sort it, every tap will get consistent pressure.
It could be a clogged showerhead, blocked pipes feeding that bathroom, or your hot water system playing up. Sometimes it’s the whole house that’s affected. Either way, we’ll track down what’s causing it and get it flowing properly again.
If you’ve got burst pipes from high pressure, major leaks, or zero water coming through, ring us straight away. Don’t wait around – water damage gets expensive fast. We’ll come out quick and sort the problem before it gets worse.
Grab a pressure gauge from the hardware store and screw it onto an outside tap. Turn the tap on full and check the reading. Should sit between 40-60 PSI. Outside that range? Give us a call.
