The GARDENA Pressure Tank Unit 3700/4 is a sustainable and powerful solution for automated water supply in the home and garden. After a simple installation, the domestic tank unit becomes an integral part of the plumbing system and allows you to use rainwater or well water for watering the garden or as service water in your household, for example for toilets. The water collected in wells, cisterns or rain barrels is moved by the powerful electric pump to where it is needed in the house and garden. The Pressure Tank Unit 3700/4 delivers an impressive output of 4.1 bar at 800 W and can pump up to 3700 litres of water per hour from a depth of up to 7 metres. It has a 19-litre water tank with a low-maintenance EPDM membrane and can be easily filled or emptied manually. A drain plug allows the water to be quickly drained from the tank, for example when frost is forecasted. The compact Pressure Tank Unit from GARDENA not only saves space, but also impresses with a robust glass-fibre reinforced plastic housing and a ceramic double-sealing system with a pump shaft made of stainless steel. An integrated thermal stop switch protects it from any risk of overheating damage. It has a non-return valve and high-quality brass threaded inserts. These aspects not only increase the durability, but also make it easier for you to use the unit as a reliable, low-maintenance permanent fixture in your home's plumbing. The practical pressure gauge always shows the current pressure in the storage tank. The additional G1" double connection outlet makes the use of the Pressure Tank Unit 3700/4 even more versatile, as you can attach high-quality original GARDENA System products and accessories.
