Meet the CGa gold...

Sometimes you just need to take the advise of others. Rather than just beat a dead horse, I took some great advise and went for new. To fight condensing, I 1) sped up the pumps 2) got rid of all the 3/4 in the manifolds and 3) increased my zones to a min of 1". The outlet and inlet temps are much closer. Due to space limits, I had to do what I had to do to get the pumps pumping away, but all is running perfect. I have never cared soo much about a room in my basement until now.

Thanks to all,

is that an optical illusion?

the gas line seems to impair the access to the electrical box. not digging at you ,just curious. you seem handy with the plumbing idea. i just wonder if cutting in a "T" ahead of the pump and tying in the boiler tank might not be benificial... oh ! i see.... it seemed you had a system pump and then zone by pump...do you require a back flow preventor or is it sort of a stand alone boiler? that is chrome paint on the street 90 or galvi?there are alot of things that i dont see done very often as i have tried my best to stay away from service work ...do people like to use bypasses on large volume systems where you live?

Timco

The gas line in front of the elect box is an old one to a abandoned fire place. It will come out. The galvi street 90 was all I could get on short notice, and a local inspector friend of mine said he would not care, but 'technically...'. I'll paint it black. The boiler is a stand alone, so no back flow protection. What exactly do you mean by cutting in a 't' ahead of the pump? I have not seen many bypasses here. (SLC, UT)

Tim if you look at the page you can find a search post and threads engine...i used to have alot of great threads saved buh ..my computer crashed and i lost all kinds of good contacts and resources be that as it may...if you search for boiler and system by passes some older threads will come up. theres lots of arrangements depending on a few variables depicted in these threads. what by passes are used for are boiler protection and mixing down temps in the field...sometimes you can find posts from a while ago by searching for a word try boiler by pass and system by pass or station by pass....maybe it is something that would be handy ...

flow control

are those flow control valves in the vertical position ? do they work properly ?? piping is a little confusing

Timco

The sales rep bragged that the taco check valves (flo controls) were universal position type. They can be used as a 90* or straight, in any position. So far, so good. No zones bleed over to the next. Had little choice with the piping...no space.

horizontal

i got a strange feeling you misunderstood the rep. or he is not correct because i believe they are strictly designed for " horizontal " piping arrangement . if you check the spec. sheet you will get my point. i hope for your sake i am wrong.

Timco

Sure hope so as well...I just checked and the pdf said 'universal' for the 220 model, as opposed to 'horizontal' for the sweat types. I emailed taco and asked. If I need to change it, oh well. Thanks for the heads up...

You mis-understood the directions. To use the flowcheck in the horizontal position the pipe enters the side port, not the bottom. The knob needs to allways be facing up.

Unfortunatly you'll need to change all of those as in the position they are now, they are doing nothing. The flowcheck works by having a wieghted flapper inside. Installed as you have them the flapper is sitting on its side.

Don't feel to bad, your not the first . We live and we learn. Do change them though as all zones will recieve heat when and one calls for heat.

flo checks

I'm a homeowner and my system was piped that way (flow checks vertically) and I was getting heat in the other zones. I bought the B&G Hydrotrols and installed them and now there is no ghosting to the other zones. It wasnt too much work to install them because they went vertically.

Those look like Grundfos

15-58 Super Brutes. If they are you do not need those flow checks as they have intergral check valves?

How can you check/service

the expansion tank? Is there clearance above it, behind it? Why not install it with a shutoff/bleeder valve in an accessible location?

Timco

I can reach the exp tank fine, even though it is against the wall. I figured it was a neat and clean place to put it and out of the way. There is an air eliminator just above it. I did get heat in all zones last night, and will need to change the checks. Oh well....:)

Timco

I just heard back from the taco rep...it's liks I am having a sale.....everything must go!!! Oh well, we learn this way.

A new twist...center spring silent check valves...avail from my local B&G dealer...threads right in...no problems anymore! Works in ALL positions.

NOT A TOTAL LOSS

DAMN GOOD THING YOU USED THREADED FLO CHECKS AS OPPOSED TO SWEAT OR THE VALVES WOULD BE GOING RIGHT INTO THE GARBAGE PAIL.

Timco

Since the supplier told me 'universal' (he even re-stated that they were for the vertical position) he ate them, pipe dope, plug, torn boxes and all. @ $46 each, that's just $279.60, that's all. The new center spring checks were just $20 each. They work great!
