Monoflow \"scoop\" tees

bobbyg_10

Assuming you have the B&G monoflo tees. It gives the Cv rating on the first page. (Their are only two pages).
If you can't figure out the pressure drop with the flow you have, just let me know which size and what flow and I can give you the pressure drop for your application.

Hope that helps.

I`ve seen them,

heck I even have a few kicking around(given to me), but I can`t seem to find any flow characteristic charts on them, any ideas?

Look at the B&G Handbook.

It's in the Library. It's all in there.

It pays to wander off the wall.

Thanks guys but,

I have that info,,these tees are different. They are 1X1X3/4" cop and actually have a "scoop" that dips from the 3/4" branch into the 1" run of the tee.
Dan, it looks like the O-S fitting you describe in "How Come?" pg 62,, but not old.

Do you have a photo, Dave?

Or are there any markings on it?

Unknown

I`ll take a pic later-on Dan,

but I may have to slice-it with my bandsaw to better reveal the innards.
The only markings on it is "Thrift", then the word "supply" w/arrow.
Obviously some knock-off thing from another country,,, I got them from Wolseley LOL!

Here you go Dan,

I cut one in half.

Thrift indeed.

This is a new one on me. Does Woolsey have any contact with the manufacturer? Perhaps the manufacturer has some engineering data for these.

Unknown

See what I mean?

I have no probs with common manufacturers,, but these lost me too.
When I heard the description "scoop tees", these came to mind.
I wouldn`t use them anyway,, I was just curious.

those

have to go on the supply side so the water diverts up the scoop. Can't use two obviously. I have used them before..China made. I prefer orfice style for flexibility.

Unknown

Thanks Bob,

I have another question though,,, if a guy was doing a large(er) zone in these,,with no data,, is sizing the pump trial & error?

Dave

Bob Bona_4

You

can try to get the Cv from the mfr., and figure the pump curve the regular way for the rest of the piping. Add them up and you have the answer.

I remember few years back, I was doing a toe kick heater in Joe Pantoleano's (Joey Pants) new kitchen. First time I used those scoop T's. Put it on the return and the kicker wouldn't heat. Was not happy. Tore it apart and swapped to supply and the light bulb went off. D'oh!

Thanks again Bob,

I`ll contact China about these Thrift fittings when the need(if ever) arises LOL!

Used them a bit

Thrift is an old company. Those scoop style tees have been around quite a while. I was using them in the early 80's. Not China made then.

Thrift also made (makes ?) Flo-controls, tank fittings, valves, etc.

Bob Bona_4

true

remember the purge valve/drains they made, Tony? They worked okay for purging only, but along came some knock off style that had no name on them. The butterfly valve was useless! water would just short circuit thru. I always had to cut in ball valves to get the system purged.

Not much info on the Ebert Machine Company / Thrift Heating Specialties website.

Thanks Andrew,

you opened my eyes,, again,,, don`t know how you ever found that!
BTW- I stand corrected, and apologize for my China cracks!

Dave

Tony_23

Sure do : )

There's TONS of them around here. Also, twin-ell balancers.
The old, original purgers worked well for what they were designed to do.
Sometimes, installing a second scoop tee backwards of the arrow in the return helped just a little.

Guess I'll have to start taking pictures of what I take for granted in a day's work

Peru Indiana

Thrift comes from Peru Indiana which is and was the home of the Thrush circulators. They used to make great check valves and other products.
