Pool Systems Introduction: Difference between revisions

As illustrated in the [[Process Flow Diagram]], water exits the pool via the drain and/or gutters.  A surge tank balances the flow from both sources.  An intake pipe near the bottom of the surge tank feeds a strainer basket that is used to catch large debris (such as leaves) prior to entering the main pump.  The main pump forces water into a bank of sand filters.  Filtered water then proceeds to enter multiple "loops" for chemical monitoring, heating (via the boiler) and chlorination.  Finally, water is returned to the pool via small outlets at the base of the gutter tray.

== Surge Tank ==

When a drain return modulating valve is not present, it is important that the drain return is restricted (the valve is partially closed).  Otherwise, flow from the drain will potentially prevent adequate flow from the gutter return.  In an ideal case, the surge tank should always have a modulating valve on the drain return.
