These 2" siphons have an 8" diameter bell and are made of 3/16" thick linear high density polyethylene with 3/4" Sch 40 PVC vent pipes and stainless steel bolts. The outlet is 2" NPT male thread. Average discharge rate varies from 30 - 33 USGPM (114 - 125 lpm).
As many engineering studies and extensive field tests indicate, continuous discharge from the septic tank should be avoided. Continuous discharge causes the distribution to be limited to a few areas within the absorption field resulting in an overloading of the infiltrative surface in these areas. In order to maintain the infiltrative capacity of the soil, alternate periods of loading and resting of the leaching system should be provided. An inexpensive and trouble-free method of achieving this solution is by using a dosing tank together with an automatic dosing siphon.
Bull run valve (only). The Bull Run® Valve is designed to split effluent flow to distribution boxes. In addition to the advantages of longer life and easier installation the valve is the most public health safe alternating device available for wastewater disposal applications. The user has absolutely no contact with wastewater due to the valve's leak-proof and external operating characteristics.
The changeover from one drainage field to another can be accomplished in less than a minute by simply turning a valve without digging or contact with wastewater. The Bull Run Valve is available in 4" and is suitable wherever septic tank disposal systems are used - in commercial, industrial, and residential application.

4" PVC gasketed "T" fitting for 3" and 4" siphons.
If electrical power is available at the site, this alternating solid state relay system can be used to sequence 3 or 4 siphons. The relays control a small solenoid air valve attached to each siphon. Opening the solenoid air valve on a siphon will start that particular siphon. Relay controlled siphon systems may be powered by solar recharged batteries.
Optional 4" NPT thread on outlet with PVC coupling (-TO), for dosing siphons.
