When do I need to install a shower pump?

A problem for many home owners when installing their new shower is to find that they are confronted with a trickle of water rather than a relaxing and powerful stream that the best showers are able to deliver. One solution to this problem is to install shower pumps or an electric water booster. In this article, we'll show you how.

Why do I have poor water pressure?

The amount of distance between your water tank and your actual shower head is known as "head". The greater the "head", the more powerful shower. Simply think about how powerful a waterfull is compared to a standard tap. One simple way of increasing the power of your shower is to increase the head either by lowering the shower, perhaps by putting in a downstairs room, or by raising the tank. Other common problems include a restriction of flow rate thanks to choosing small diameter piping in your shower system or that your shower head is simply blocked or otherwise restricted. If you check all of these common areas for improvement and find that your water pressure is still too low, then you have no option other than to install an electric shower pump.

Installation

When choosing a booster pump, look out for units that boast brass impeller pumps. This devices can improve the water flow rate by up to 25 litres per minute. The installation of these units is generally quite simple. There are four ports on the pump, two for hot and cold water in, and two for hot and cold water out. These are usually plumbed in using flexible hoses to allow discrete location of the pump. When connected the cold water in, make sure that it comes from a cold water storage tank so as to negate the pressure fluctuations from a rising main. Similarly, check to see that the water pressure on the hot and cold water side are as similar as possible before installing the pump. Ensure that the pipe outlets from the pump are facing vertically upwards to prevent air from getting into the system. Similarly, make sure you are using at least 22mm piping wherever possible to prevent unnecessary pressure drops. Wherever devices mix electricity and water, there is a potential for injury. Ensure that the electrical system of the pump is installed by a properly qualified competent person. This should be installed to British Standards 767 and conform to section P of the building regulations. The final consideration is to strike a balance between discrete location and one which can be easily be accessed for maintenance and cleaning purposes. You may find that you need to build a small wooden enclosure around the pump.

The benefits of low flow toilets

Prime among the many benefits of low flow toilets is water conservation. It doesn't take a rocket scientist to figure out how does a toilet work, but the concept of low flush toilets has given rise to many design changes and innovations, such as pressurised air in toilet tanks and dual-flush valves. Even toilet bowls and toilet pans have undergone design changes as a result.
