Buying Guide

What is a water pressurizer?

A water pressurizer works with the objective of solving low water pressure problems in cisterns, water tanks, and poor municipal supply pressure. The pressurizer is an electric pump with a controller that can work manually or automatically.

How does the water pressurizer work?

The pressurizer can be always on, activated manually, or activated automatically. In an automatic implementation, as soon as a consumption point is opened, such as a sink faucet, the pressurizer pump starts to work; when the point is closed, the pressurizer turns off.The product offers more water pressure and improves the pressure supply to homes, parks, offices, or industries.

Where to install the water pressurizer

You can use the water pressurizer at different filling locations, regardless of the type of cistern or characteristics of the water tank. Installation sometimes takes place at the bottom, next to or above the water supply network, depending on the type of project. For these and other reasons it is better to install the product with professional assistance.

What is the difference between water pressure switch and flow switch?

Most models on the market work in two modes – flow switch and pressure switch – there are implementations that work better with a flow switch, others are better for pressure switch.

Flow switch

A flow switch pressurizes the moment you activate the flow of water. It is responsible for generating the pressure or “push” that the water needs to circulate.

Pressure switch

Unlike the flow switch that works only when the water outlet is activated, a water pressure switch has a continuous operation to maintain a constant pressure in the hydraulic network.

Continued pressure reduces the time for pumping to take place. In the water pressurizer, the pressure switch takes less time for water to arrive after opening a tap than in the pressure switch models.


A water pressurizers can cost from $150 to $1,500. The brand represents the main factor in increasing the cost, as well noise level the pump makes.

Where to buy?

Many hardware stores will have a small selection of water pressurizers; however, for a larger selection, you will have to go to a specialized industrial supply or search at online retailers.

Purchasing Criteria

Here are the main criteria upon which to choose a pump:

  • Noise
  • Points of delivery
  • Corrosion
  • Warranty


One of the main complaints of people who buy water pressurizers is the pump noise. Some versions make noise only when the water outlet is activated, while other productions have a constant noise that can be very disturbing at night. If the pump is anywhere near a point where it might be annoying or disturb your sleep, consider paying extra for a quieter pump.

Points of delivery

Do you need to pressurize your entire home? Or are you just looking to increase the pressure to your bathroom shower or washing machine? It is not acerbically required that you install a large pump to pressurize your entire house. If you are on a budget, consider purchasing a small pump just for specific applications in your home.


A quality water pressurizer is one built with all corrosion resistant materials. Some materials that exist in pressurizers with resistance to corrosion are: aluminum alloys, elastomers, thermoplastics, stainless steel, brass and copper.


The 3-month warranty period is the minimum guaranteed by law. However, given the work load of these pumps consider buying from a company that will services it’s products for longer and provides a replacement guarantee.
