Watermill ANHBP65D

The WRAS-approved Watermill 2 Bar Twin Universal Brass Shower Pump is specialized for enhancing shower and basin tap water pressure within residential plumbing frameworks. It elevates the pressure levels, ensuring a fulfilling shower experience, especially with rain-type shower systems, pushing up to a peak of 2 bar pressure.

This version of the pump is notable for its universal head, adaptable for configurations either both positive and negative head applications. Under positive head conditions, the water flow is automatically assured, with the source (like a cold water tank) positioned higher than the pump, ensuring gravity-fed water supply. But with negative, the pump pulls the water because the source is either at the same level or below the pump. 

Usually, cold water tanks are in a home's attic. The Watermill 2 Bar Universal Shower pump can push water to higher spots, useful if you've turned your attic into living space. Just remember, the pump needs a tight connection without air getting in, or it won't pressurize properly.

Crafted from brass and stainless steel, the pump is conducive for clean water transfer, eliminating the risk of rust contamination. It's equipped with a dual impeller, enabling concurrent transmission of hot and cold water. This function permits uncompromised, robust water flow, allowing seamless, simultaneous activities, such as one individual showering while another uses the basin. Additionally, its design incorporates anti-vibration and non slip feet for quiet operation.

UK regulations forbid connecting these pumps directly to the mains water supply to prevent unintended consequences on the communal water pressure, affecting neighboring premises.

How the Watermill 2 bar universal shower pump functions The pump operates responsively, activating or deactivating based on water demand, as it perceives pressure alterations in the piping. It activates when a tap is turned on, reacting to the resulting drop in pressure. The pump ceases operation when the tap is closed, restoring the system to its normal pressure level.

Water flows into the cold tank and splits into two paths: one goes to the hot water tank for heating and then to the pump, and the other goes straight to the pump. The shower pump boosts the water's speed, resulting in a stronger output from the tap.

The following picture shows a situation where the pump doesn't need to suck in water because it's already being fed by gravity; this is called a positive head. However, if the pump is at the same height or higher than the water storage, it must work harder to draw water towards it, creating what's known as a negative head situation.
