1

What are the main components of a typical circulation system (in order)?

1. Balance tank
2. Pre-pump strainer
3. Circulation pump(s)
4. Filter(s)
5. Heat exchanger

2

What is the purpose of the pre-pump strainer?

Prevents small items of physical pollution from entering the circulation pump (where it would cause damage).

3

What is the purpose of the circulation pump(s)

Moves water around the circulation system.

4

What is the purpose of the filter(s)

To trap pollution within the filtering media (which is usually sand) to prevent it re-entering the pool water.

5

What is the purpose of the balance tank?

To provide a 'reserve' of water. This keeps the pool at a consistent depth.

6

What does 'flow rate' mean?

The rate at which water is travelling through the circulation system (usually in cubic metres per hour).
