Flo-Chek Waranty Terms

For more than 40 years, designers and installers accept used Taco Flo-Cheks in forced hot h2o heating systems to prevent gravity apportionment during periods when the banality is hot, but the space heating zone is non wanted. This makes it possible to employ the heating boiler to maintain domestic hot water twelvemonth-round. You tin also use Flo-Cheks in systems with multiple circulator zones to allow heat to menses only into the zones that are calling for heat. In addition, the thumb screw tin can be opened manually for gravity feed applications, if the primary circulator stops operating.

Features Include:

Automatically Opens When Circulator Starts Running
Bandage Iron, Universal Body or Bronze Sweat-In Configuration
125 PSI Maximum Operating Pressure (862 kPa)
277º F Maximum Operating Temperature (136º C)

Oft Asked Questions

Q.	Why does my Flo-Chek leak past? Typically this is caused by debris accumulating on the deejay or seat. This would be the case if the valve worked fine when it was get-go installed. You will have to take the valve apart and clean the seat, disk, and stem to bring the valve back to original. The stem should be vertical.
Q.	Why is my Flo-Chek or MPV noisy? Ordinarily a check valve is noisy if the valve is oversized for the flow going through the valve. The flow cannot elevator or swing the disk all the way open up so the disk bangs back and along within the body of the valve.
Q.	Why does my hot water circulate when my Taco pump is off? Something has adhered to the Flo-Chek seat or disk. The Flo-Chek is a weighted deejay bank check valve that ordinarily prevents thermosiphoning. That is, it prevents the lighter, hot h2o from rise to the radiations and the heavier, absurd h2o from sinking, causing a flow in the system without a pump. If the system worked fine before and then started to human activity up, the disk is stuck or something is on the seats.
Q.	My house has five zones, each with its own circulator. Hot h2o is passing into zones that are not calling for heat. Do I take some defective circulators? If you are non using zone valves, you lot demand either Flo-Checks or a circulator with an Internal Flow Check (IFC). This is required to forestall thermosyphoning, a condition in which lighter, hot water rises, and heavier, cool water sinks, causing a catamenia in the system.
Q.	I take a 3-zone residential organisation with a 219 Flo-Chek on each zone. The manual override thumb screws are all open up ~2 turns. Should these be fully closed? The bypass knob should be turned clockwise all the style for normal operation. For featherbed mode, thurn the knob counterclockwise until you have reached the position desired.
