Commercial Plumbing: How to Improve Low Shower Pressure Plumbing Solutions from Laser Plumbing Wellington East

Low shower pressure is one of the most frustrating plumbing problems homeowners face, especially during busy mornings. If your shower is delivering a weak stream of water, it can affect comfort, efficiency, and overall water usage. Fortunately, there are a number of effective solutions that can restore or improve shower pressure in your Wellington home.

Low shower pressure can result from various issues. It could stem from an outdated or poorly maintained plumbing system, undersized piping, or an older low-pressure hot water cylinder. In some cases, the incoming water pressure from the council supply may also be lower than ideal. It is important to have your system assessed by a qualified plumber to determine the exact cause.

Ways to Improve Low Shower Pressure

Upgrade to a Larger Supply Tank or Piping
If your home’s pipework is outdated or too narrow, it can restrict water flow. Installing larger bore piping or increasing the capacity of your supply tank can significantly improve pressure.

Replace the Shower Mixer
Installing a new shower mixer, especially one designed for low or unequal pressure systems, can help balance and boost the hot and cold water mix. This upgrade typically costs between $600 and $1,500, depending on whether wall linings need removal.

Convert to Mains Pressure Cold Supply
Switching the cold water supply to mains pressure and changing the mixer accordingly can improve the shower’s performance without replacing the entire hot water system.

Upgrade the Shower Rose
Sometimes, the issue is simply the showerhead itself. A high-efficiency shower rose can enhance flow without the need for major plumbing changes. Costs range from $350 to $650 depending on the product.

Install a Booster Pump
If other options aren’t sufficient, a booster pump can increase water pressure directly. These installations generally range between $1,200 and $2,200.

Switch to a Valve-Vented or High-Pressure Cylinder
Replacing your current low-pressure hot water cylinder with a valve-vented, medium-, or high-pressure version can significantly enhance pressure. Pricing varies between $1,285 and $4,700 depending on the chosen system.

Consider Alternative Water Heating Systems
Switching to a gas continuous flow water heater or a heat pump water heater can also improve pressure while offering long-term energy efficiency. These upgrades range from $3,500 to $8,500 depending on the system.
