Some pumps, such as the [[EMAS pump]] are deep well pumps, and can pump water over a height difference of 40m. Others, such as the [[Canzee pump]] pump water up to 12-15 m deep. The DTU pump is used for extracting water from underground rainwater catchment cisterns.

Because of their lightweight and low-cost design, PVC pumps are mainly suitable to be used by families or small groups of families. PVC pumps are not recommended for use by large groups of people, as this will lead to the need of frequent maintenance. An excellent overview of community hand pumps, which are suitable for larger groups, is available at the RWSN website<ref>[http://www.rural-water-supply.net/en/implementationsustainable-groundwater-management/handpump-overview pumps Overview of community handpumps at the RWSN website]</ref>.

These pumps are very popular for domestic use, as shown by 20,000 water systems in Bolivia, which are made with locally available PVC tubing and valves made with marbles. PVC pumps are used in Malawi and Brazil and many other countries in combination with water storage tanks, for example in the kitchen. When used with a storage tank near the roof in a kitchen, running water becomes available in the kitchen, often considered a great luxury.
