Public pool basic plumbing

 

The additional booster pump should be 

installed after the filter, using a “T” joint on the main filtration pipe. 

The automatic control commands both the booster pump and the 2 way valve after it. (The 2 way valve is 

installed in order to prevent undesired low water flow through the collectors caused by the main filtration 

pump). 

Public pool basic plumbing 2

 

When there is a need for total separation between the solar piping and the filtration piping it is advisable to 

pump the water to the collectors by an independent pump that takes the water directly from the pool and 

returns the heated water directly to the pool.
