Will this Work?

Should be no problem Jason.

How is your air issue working out?

hi here is a picture of what i want to do the red pump will be for the dhw and the green one i would like to pump right into a 5 loop ez header with 1-1/4 supply and 3/4 takeoffs home run no zone valves constant circulation

my question is can i cap the 5th one and just use 4 loops or would i need to have a pressure differential bypass

the loops will serve 2 baseboard loops and 2 panel rads

id like to save the 5th one for future use like an addition on the back of my house

hi mark thanks for asking i took the fill apart today to see if the strainer was clogged the bowl was a little brown at the bottom but i flushed it and cleaned it and put it all back together and purged the system again and all is good now the pumps are whisper quite again ;-)

i just hope i don't have to purge this thing every week ;-)

thanks mark hay I'm not to far from you maybe we will see each other at a trade show or something

We may


Reason I asked about your water source is because I ran into a situation a year or two ago when we installed a Voyager on a well system.

ABSOLUTELY THE WORST WATER I HAVE EVER COME ACROSS! The CO2 in this water was so high, you could bottle it right out of the tap and and sell it as Club Soda. The system would go air bound in minutes! UUGH!!!!!! Luckily, the HO had a point driven that was not CO2 laden. Thought I was going to have to get the fire dept. over to fill the system!

I will say this, I will never use another circulator that has a flow check device in the volute. NEVER. Even when your done purging you're not.

i agree it's hard purging a pump with ifc.

with the 15-58 i can get it with 3 speed and take the ifc out of the pump and just add one after the pump?

thanks

15-58 fc


Never had an issue with those pumps. The FC is in the outlet.

We have replaced nearly all of the Taco IFC's with Grundfos 15-58fc's. Problems gone.

To Taco's credit, the new IFC's are now positioned in the outlet.

oh that's why okay well i am buying 2 new 15-58fc when i redo my manifold. what do you think mark since this is a small house should i also balance each loop with balancing valves it's 2 baseboard loops and 2 panel rad's

In critical applications

Where the check valve is particularly critical (ie. Tekmar 260 type build-up), I do not trust the small plastic check valves in the UP15-58FC pumps. I recommend using a brass check valve and removing the plastic one. It costs more, but is more trustworthy. We have seen them fail, particularly in high temperature (solar) applications.

Header and balancing valves

It looks like you've got a black iron header serving both hydronic heat and DHW. I don't know your local codes, but I wouldn't do that if only for the reason I don't like rusty water. Yes, re-do the header with copper "L" tubing, and add the balancing valves while you're at it. The first time the temp goes below 10f, you'll be glad you did!

hi john the dhw pump just heats the dhw tank i don't drink the boiler water. you must think that the red pump is for dhw recerc? but it's not it's to heat my dhw tank

and even if i piped it in copper the boiler is still cast iron. and i still would not trust the water.

i just think piping in copper is allot easier then black iron this is why i want to use the EZ header so i don't have to change everything from the boiler over to copper when most is in black iron now.

so i will just stick with black iron and use EZ Header it will save me time

and i will use copper for all the loops and ball valves

what would be good balanceing valves to use for my system?

thanks
