Just Moved In? Here's How to Fix Low Water Pressure in a New Build

Jun 09, 2025 Posted by: Ben Jackson Extend your home

New build homes promise modern living — smart layouts, clean finishes, and energy efficiency. But there’s one common frustration for many homeowners: poor water pressure.

From slow-filling baths to disappointing showers, low pressure in a new home can be a daily annoyance. Here’s why it happens — and what you can do about it.

Why Is Water Pressure Often Low in New Homes?

There are a few common culprits behind low water pressure in new builds:

1. Shared Supply Lines

Many new housing developments use shared mains water supplies. This can result in reduced pressure when multiple homes draw water at the same time — especially during peak hours.

2. Water-Saving Fixtures

To meet efficiency standards, new homes are often fitted with low-flow taps and showerheads. These can restrict flow more than expected — great for the environment, not so great for performance.

3. Long Pipe Runs

If your property is located at the end of a development or far from the main supply, water pressure naturally drops over distance — especially through smaller bore pipes.

The Symptoms: Is It Just You?

Here’s how to know if your pressure is too low:

  • Shower flow is weak or cuts out when another tap runs

  • Washing machine or dishwasher takes longer to fill

  • Toilets fill slowly or don’t flush with full force

  • Tap flow is slow, especially upstairs

If that sounds familiar, it’s time to act.

How to Boost Water Pressure in a New Build Home

You don’t have to live with poor pressure. Here’s what you can do:

✅ Check Your Stop Tap

Make sure your internal stop tap is fully open — partially closed valves can restrict flow dramatically.

✅ Install a Water Pressure Booster System
