TACO Flow Chk

Confused_2

The instructions on the box for a TACO flow check show that the flow check must be a minimum of 12" downstream of the circulator. Yet the pictures displayed in the heating forums never show this being followed. Is it important???

ALWAYS follow the manufacturers instructions. they made it they designed it and they gaurantee it. do you know more about it than them??? read instructions ---then procede

And what do you do

if you do not have space for the 12 inch minimum between circ and flowvalve ? With Taco it is a best case situation to follow , like the 24 inch minimum for an air scoop . After thousands upon thousands of flowvalves piped with a close nipple above the circ , I cannot remember having a flowvalve problem or failure .

bob young

in that case use a bell & gossett. they have less rules. lol

Ahh

I did not know that . Actually , until last year , I didn't know about the 12 inch minimum rule on the Taco flowvalves . I was sitting on a bucket eating lunch and didn't have nothing to read , except the Taco box . Live and learn .

taco flow checks

The new taco circulators come with flow checks installed in the housing.I guess they work good if the circs are installed on the supply side of the boiler,but when installed on the return side they don't work so well.

Taco IFC circs

I agree! I just installed three of these gems on a return, today. I have used these units on supply side pumping with no problems. On the return side, I had to remove the flow checks because the zone with the least amount of head pressure refused to pump. I figure that the zones with higher head pressure were causing some reverse flow and prevented the circ on the lower head pressure zone from opening up. Live and learn!!!
