<ul><li>The rope pump is "too simple", therefore it is easy to copy, but experience indicate "Simple is not easy".<br/li><li>If not made well, the pump breaks down to much and can not be easily repaired.</li><li>Many Introductions have failed because of lack of training of users in maintenance and production and installation errors,so the pump parts wear out too fast, or parts break<br/li><li>With different depths, different sizes of pump pipes are needed, otherwise the pumping becomes to heavy. See manuals on websites of Practica Foundation and Connect International.<br/li><li>The pump needs a “blocking system” on the handle to avoid return of the handle, which can be dangerous for children.<br/li><li>Compared to piston pumps the rope pumps splashes more. <br/li><li>Similar to Piston pumps, a cement slab and a good soak away are needed to avoid splash water becoming a cause for pollution.</li>
