Description

The integral design of the Taco 3450 Combi Valve combines a cartridge style backflow preventer with a pressure regulating cartridge style boiler feed valve into a unique one piece body configuration. Taco’s 3450 combination dual check backflow with atmospheric vent and boiler feed valve with purge auto-reset, dial in pressure setting and adjustable indicator sets a new standard for performance and serviceability.

Designed for use in hydronic heating systems the duel check backflow prevents heating system water from flowing back into the supply water piping if the supply pressure falls below the heating system pressure. The boiler feed valve automatically fills or refills (make-up water) the closed heating system to the desired cold fill pressure. Both the backflow and the feed valve contain cartridges that can be serviced or replaced without draining the entire heating system.

Features
  • Auto Reset from Fast Fill
  • ASSE 1081-2014
  • Simple Pressure Adjustment
  • Servicable Cartridge for both the Backflow and Feed Valve
  • Adjustable 360 View of Pressure Indicator
  • Large Adjustment Range
  • Serviceable without draining the system
  • One Piece Body Construction
  • Stainless Steel Strainer

Nice all-in-one unit

Seems to work as advertised. The instructions included with the valve, however, have some errors in the section on adjusting the pressure. The lock knob is at the bottom of the adjustment knob, NOT on top of the unit. Also, the figures showing the direction to turn for increasing or decreasing pressure are reversed.

I think this device saved me

Not only is this a multiple function device but it (I think) provided me some freeze protection. There is a plastic clap that is threaded into it that blew off. Thus it gushed water as a result of the boiler going off due to a power failure in a deep freeze. Water gushing was horrible but I think because water was allowed to flow through the system it was saved. The only complaint I would have is, why couldn't I buy a new cap?

Good so far

Good so far. On the first one I got a little weeping from the top plastic cap. Instructions indicated that may happen but I recall it being vague.
