Domestic water supply system TGP 1025 E

Service water pump permitting the utilization of alternative water sources in your household and thus saving drinking water.


You would like to be independent of the drinking water network and use rainwater for your domestic water supply? Your remote holiday home is not connected to the municipal water supply network? If so, the domestic water supply system TGP 1025 E is just what you need!

The powerful 1,000 W domestic water supply system TGP 1025 E with integrated pressure tank (19 litres) pumps free service water fully automatically through the entire house. The pump can easily be integrated into an existing water network and permits the economic utilization of rain or ground water regardless of a connection to the regular drinking water system.

High conveying capacity

With a conveying capacity of up to 3,300 litres per hour the pump can extract water from a pool, well or cistern so as to use it for, say, toilet flushing, the operation of a washing machine or of sprinkler systems in front yards or kitchen gardens. The compensation tank ensures a constant pressure of 3 bar within the system. Both suction and pressure connection come with a thread that has a diameter of 1'' or 3.33 cm (G1).


The pump housing is splash-proof from all directions as per protection type IPX4 and made of impact-resistant plastic as well as of metal coated with protective paint. The high-quality face seal, the two robust metal threads at the suction and pressure side, the maintenance-free aluminium winding motor featuring a high corrosion resistance and the integrated thermal protection circuit that prevents overheating all ensure a long lifetime of the domestic water supply system.

Simple operation

Particularly convenient application is facilitated by the large inlet opening for easy filling of the pump and the practical on/off switch at the side of the pump. If the domestic water supply system is not used all year, it is essential to drain all water from the pump housing prior to storing it away for the winter. For this purpose the TGP 1025 E is fitted with a water drain screw through which the housing can easily be emptied so as to protect the pump from potential frost damage. For permanent stationary application the domestic water supply system can be firmly affixed via bore holes in the pump foot.

Functional principle of the pressure tank

The pressure compensation tank plays a vital role in the automatic water supply using our domestic water supply systems. The larger the dimensions of the pressure tank, the less frequently will the pump need to switch on. Consequently, the water reserve within the pressure tank avoids the unnecessary starting of the pump when withdrawing only small quantities such as a glass of water. The larger the tank, the more fluid does it hold and the less frequently will the pump need to switch on. Seeing as each start-up of the pump requires energy, this reduced switch-on frequency also means a reduction in the energy consumption and costs. Moreover, fewer switch-ons ensure a more sparing system operation with reduced wear. The noises caused by the start-up and operation of the pump are equally reduced.


Including alternative water sources for the daily use in your home's water supply network is only reasonable – both from an ecological and economical viewpoint. After all, you can save money with every application of the pump. Not only is it much less expensive to water your garden during the summer with pumped, non-potable service water as opposed to with purchased industrial water – the alternative water supply for flushing the toilet can be ensured all year round. You can also run your washing machine on rain or well water. And it pays!

Practical example

With an average of 250 washing cycles a three-person household consumes more than 18,000 litres of drinking water per year. On top of this, approx. 43,000 litres of water are flushed down the toilet and 1,750 litres are used for watering in the garden. This totals up to more than 62,000 litres which represents 50 % of the average water consumption of a family of three. An enormous savings potential that can be exploited by using the domestic water supply system TGP 1025 E.

And this benefits you in more than one way! Drinking water from the tap is often limy. On the one hand the minerals contained in the lime are beneficial to our health, at the same time, though, the hard water leads to limescale in household appliances thus reducing their service life. Soft rainwater on the other hand goes easy on your washing machine which extends its lifespan.

Possible applications in your home and garden

What you garden needs above all else during the summer is water – plenty of it and at regular intervals. In addition to its application for the domestic water supply the domestic water supply system TGP 1025 E can also be connected to all customary sprinklers and irrigation systems via the practical universal connections: Ranging from the individual garden hose fitted with a spray gun for the manual watering of plants to the fully automatic watering of your lawn and entire garden by means of sprinklers and irrigation systems. At the push of a button the powerful 1,000 W pump TGP 1025 E delivers free service water – amongst other things also for work with a high-pressure cleaner, e.g. to clean terraces or walkways or as a means to car valeting.

The annual savings profile is rounded off with the domestic water supply system's high energy efficiency. The pressure stored within the solid pressure tank of the TGP 1025 E permits many small water withdrawals without the pump starting each time. This significantly reduces the switch-on frequency, the pump is spared and the energy consumption noticeably reduced.

The general rule is:

When no drinking water quality is required, the domestic water supply system can be used as alternative water supplier for your home and garden. The tap water of your local supplier is simply replaced by pumped free, non-potable service water.

Here we show you how to calculate the required capacity of your domestic water supply system:

Only a few calculations will help you determine the performance capability of the respective domestic water supply system required for a specific application purpose or a planned installation. The two decisive factors are the required delivery head and flow rate.

The necessary pressure can be included via a simple conversion into the delivery head. First, you need to calculate the required flow rate, i.e. the maximum water consumption, based on the following specifications:

Device Litres per minute Litres per hour
flushing cistern 4 l/min 240 l/h
sink 6 l/min 360 l/h
dishwasher 8 l/min 480 l/h
washing machine 10 l/min 600 l/h
shower 10 l/min 600 l/h
bath tub 15 l/min 900 l/h
sprinkler 10 l/min 600 l/h

Example: If one installation shall be sufficient for the simultaneous water supply for one washing machine (10 l/min), one dishwasher (8 l/min), one bath tub (15 l/min) and two sprinklers (2 x 10 l/min = 20 l/min): Sum up the corresponding consumption values – in this example we end up with 53 litres per minute. The ultimately required flow rate always corresponds to 40 % of the calculated result. This means, the actually required flow rate in our example amounts to 21.2 litres per minute. Now multiply this value by 60 and the obtained product indicates the amount of water required each hour: 1,272 l/h.
