'''Trademarks:''' AID Suction; Bandung, Inalsa Suction; Jetmatic Suction; Lucky, New No. 6; Rower, SYB-100; Wasp, etc.

'''Public Domain:''' [http://www.rural-water-supply.net/en/implementation/public-domain-handpumps/no-6-pump No. 6 Pump] ===Suitable conditions===

'''Range of depth:''' 0–7 m.

7 m of the surface.

===Construction, operations and maintenance===

The operation begins with priming the pump, by pouring clean water on the plunger through the top of the pump stand. Pumping is done by moving the handle up and down, usually while standing beside the pump (with a rower pump, the user sits). Most suction handpumps can be easily operated by men, women and children.

'''Potential problems'''<br>

— worn out washers, cupseals and bearings;<br>— excessive corrosion that causes pump rods to break, and leaks to appear in the rising mains;<br>— many pumps are of poor quality;<br>— the biggest drawback of suction pumps is that they can lift water to only about 7 m, and if the water table falls below that level, the pump becomes inoperable and must be replaced with a deep-well pump;<br>— contaminated water is often used to prime suction pumps;<br>— most pumps are designed for family use and are not sturdy enough for communaluse.<br>

===Costs===

From US$ 35 (Thailand, 1985), including 10 m galvanized iron drop pipe and a foot valve, to US$ 185 for a Wasp pump in India (1983 price without a suction pipe).
