The objective of this tutorial is to make a manual pump which can be used for getting water out of a tank.

For the piston:
The pump works on a very simple concept.
A vacuum is created when the piston is raised.The other valve is the opposite way round so the water from the outlet is not sucked in.
Pressure is created when the piston is lowered which then closes the non-return valve at the bottom and opens up the other valve. This allows the water is to flow out.
This type of pump is called a ‘displacement pump’.
The aim of this step is to check the equipment is in order without gluing the components together.
Slot the components together as per the following diagram:
You can even check if it is working or not.
For best results: the areas circled in blue must be as short as possible.
Once all checks have been completed, you can now start to assemble the components.
All that needs to be done is to glue the parts together using PVC glue and to check if the connections are watertight .
It will take about 1 hour to dry. However, if the water is intended for consumption, it is then advised to wait between 12 and 24 hours for any toxic solvents to disperse.
Glue all the parts together and once they have dried, drill a hole in the middle of the 50mm-50mm coupling.
A nail could also be used (see image) by drilling a hole of a smaller diameter.
This allows the marble to be sufficiently elevated to allow the water to flow freely, preventing any obstruction at the other end.
/!\ Take care to ensure that the marble is at the right end!
Ideally, seal the tubes for maximum efficiency. At SERTA we have set the static part in concrete which forms the cover to the tank.
The important things to take into consideration are that the extension tube, where the water goes into the system, should not actually touch the bottom but needs to be within sufficient proximity to allow the water at the very bottom to be sucked up and that the whole of the system is fairly rigid to allow a pumping action.
