Siphon Retrofit using the CueBox
A retrofit of two failed alternating
siphons with two 4 inch diameter Flouts, one with 17 inches drawdown, the other with 22 inches. drawdown. Location: Geneva, NY Date: November 2008
|
The original dual siphons had failed. After removing
the chamber lid, the old siphons were cut out.

| The old siphons were removed |

|
New plumbing was connected to the old siphon vents and the old traps were filled with mortar. The new
connections were made by foaming in the new pipe stubs with urethane foam in a can (Great Stuff) and then topping off
with hydraulic cement. New connections were usable within a hour. Solid concrete blocks secure the CueBox and form landing
pads for the different drawdown Flouts.

| New piping installed to connect Flout system |

Total install time was less than 6 hours. A down
turned inlet pipe stills the incoming flow from the pump chamber. A 1/4 hole under the elbow prevents back siphoning.

| New system goes right to work |
