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 Grundfos STP 3.0 Bar Shower Pump, certified by WRAS, can be positioned between your house's water pipes to augment water pressure during showers or when you open the washbasin faucet. It amplifies the water flow, allowing for a more robust flow. Its maximum pressure capability is 3 bar. This pump operates with a positive head, indicating the water's natural flow towards it. The originating water source, typically a cold water reservoir, is positioned at least 1 metre higher than the pump. The gravitational pull from the reservoir ensures the water flows effortlessly into the pump. This design means it works more efficiently than a pump with a negative head, as it doesn't need to actively …
