The Circulation System

Question 1

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

Answer 1

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

Question 2

What is the purpose of the pre-pump strainer?

Answer 2

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

Question 3

What is the purpose of the circulation pump(s)

Answer 3

Moves water around the circulation system.

Question 4

What is the purpose of the filter(s)

Answer 4

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

Question 5

What is the purpose of the balance tank?

Answer 5

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

Question 6

What does ‘flow rate’ mean?

Answer 6

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