DAB is one of the best-selling brands of water pumps for consumers as well as for professionals. These pumps adhere to a very high standard of quality, with each pump being tested manually by a staff member before it is put on the market. This is the only way DAB can guarantee that you obtain the absolute best. They have a solution regarding almost any situation, whether it involves an industrial application or simply spraying a garden. DAB's professional quality is also reflected in its consumer line. The DAB pumps we replace for people are usually over ten years old.
This pump switches on or off automatically if you open or close a water point that is connected to the pump. In many cases, this feature is a considerable advantage: for example, when irrigating a garden with a hand-held sprayer, or supplying a toilet or washing machine with rainwater. It is also useful if you want to increase the water pressure in your home. Unlike standard garden water pumps, water pressure pumps - because of the difference in pressure - 'notice' when one or more water points are opened or closed. This is how the pump knows that it needs to start or stop. Standard water pressure pumps (which are mounted to a tank) are equipped with a mechanical switch, and the more advanced ones have electronic switches. Both systems have advantages and disadvantages. The mechanical switch is reliable but can either not be set or it is difficult to do so, while the electronic version can be set but is dependent on electricity.
This pump is equipped with a water tank, which may be handy in a number of situations; for example, if the pump needs to supply water occasionally (drip watering). In that case, a pump without a tank will start pulsating (continuously switching on and off). A pump that is fitted with a tank can supply water from its tank so that the pump does not need to switch on immediately. Such pumps are very handy to use with, for instance, irrigation tubes and controlled irrigation, or for filling a toilet reservoir, which is usually also a gradual process. A second advantage of a tank is that it greatly reduces water hammer, the hydraulic shock - or ‘blows’ - that water pipes experience if a water supply point is opened hard and fast. Pumps that provide instant high pressure may increase instances of water hammer, and are therefore equipped with a (built-in) tank.
If there were one brand I would recommend to my clients, it would be DAB. So far, I’ve installed dozens of this brand of pumps, and never experienced actual problems. Particularly the aquajet does a great job in rainwater reservoirs.
Indeed, short pressure boosting activity after installing the DAB pump and a 18 litre pressure valve, but followed by hammer in my pipes and a lot of trouble. Had to disconnect the entire system. Wasted all my money. Think wisely before you buy this pump. The pump may seem simple on paper, but the situation is completely different in practice. <div class="review-comment-admin"><div class="review-arrow"></div><p class="comment-title">Reply from Waterpump.co.uk:</p><p>Dear Mike. Thank you for your review. We understand this is a pump that was purchased from DAB several years ago and therefore introduced them to you. Maybe the pressure in your pipes became too great. All current booster pumps are all equipped with a pressure regulator to prevent this from happening. It may be a good idea to involve a specialist for installing the system.. </p></div>
After much consideration, purchased this pump to supply ditch water to the garden (irrigation and draw-off points). Pump purchased as a kit with a suction hose, etc. Punctual delivery. Needed to concentrate on proper installation and connection. Plug into the socket and run. Has now operated very satisfactorily for several weeks.
