The air vent on the T40SP Side-Pod helps create a smooth transition for water flowing in and out of the tanks.

 

For Standard Flow installations the lid for the T165XP includes air venting. For High-Flow installations additional venting can be added by connecting a vent pipe to the
“Overflow” port.

 


The overflow allows excess rainwater to go out of the overflow rather then puddling up at the base of the water feature.

How the Overflow Works:
When the system is turned off, water in the stream refills the Filter Tank and Expansion Tanks to the bottom of the “Overflow” port. Rain water will replenish any evaporation loss until the water level in the Filter Tank rises to the bottom of the overflow. Excess rain water will now flow out the overflow to prevent a standing pool of water from developing over the top of the gravel when the system is not in use.

 

Drain to Daylight
Route the overflow pipe to drain onto an existing slope. This is suggested when you have a slope in your landscape that supports excess water run off.
Drain to Storm Drain
If you can’t drain to above ground, tie the overflow pipe into a existing yard drain or downspout drain.

Note: If neither of the above options are possible, excess rain water can be drained into a gravel swam p at a location away from the Filter Tank.
