What's the diff between a regular ball valve and a true union ball valve?

Nanook · 09/03/2008, 10:51 PM

good question

Angler02 · 09/03/2008, 10:56 PM

HAHA

Nanook · 09/03/2008, 10:57 PM

I amuse myself

Angler02 · 09/03/2008, 10:58 PM

But your were sure that I needed them. HAHA

Nanook · 09/03/2008, 10:59 PM

I know what they are but do you????

I sure don't thats why I asked. I am sure that I have seen them and do know but I can't put a picture in my head.

logiktest · 09/03/2008, 11:01 PM

Know what a union looks like? Know what a ballvalve looks like?

Merge the two together, and you get a TUBV.

Also, if your thinking about using these in your plumbing scheme, be sure upsize the plumbing.

Angler02 · 09/03/2008, 11:02 PM

Ok see I know what a gate valve is!!! You should have said that.

Angler02 · 09/03/2008, 11:03 PM

I believe that the returns are 3/4 and the drains are 1" 1/4

Nanook · 09/03/2008, 11:04 PM

Scroll down!

With a TUBV you can disconnect a pump or sump from either side and keep the flow stopped with the ball valve....ultra convenient but pricey.

Angler02 · 09/03/2008, 11:07 PM

That is pretty neat. I don't see a need for me to have those though. I don't have a $40,000 dollar system. I am ballin on a budget.

No, thats different. One valve mechanism closes like a gate, while the other closes like a ball with a hole in the middle.

logiktest · 09/03/2008, 11:10 PM

3/4" unions cost about 2 bucks, Baller...

Angler02 · 09/03/2008, 11:10 PM

I will probably use 4 different regular ball valves. One one each return and one on each drain. Or maybe just one on my return. I don't know yet, I have to sit down and make a shopping list still.

Angler02 · 09/03/2008, 11:13 PM

The TUBV is $14.25 a piece for 3/4". If I had a need I would get them. Regular ball valves have always worked for me. Remember you are talking to a guy who still uses an overflow and is damn happy with it.

logiktest · 09/03/2008, 11:18 PM

You probably (it's unlikely) won't need them on the drain side.

You would be well off to use a ball valve and a union on the return though... Valve to regulate flow. Union to easily remove the pump for your regular cleaning/oiling service.

chadfarmer · 09/03/2008, 11:18 PM

true union has a union on both sides plus a ball valve in the middle and are beefier

Where in the world are you shopping for these!? And what material are they made of, Diamond coated titanium?

Are you planning to use all SCH80?

Angler02 · 09/03/2008, 11:24 PM

I will be using unions on all of my drains and returns to make for easy removal. Canyou get unions at Home Depot or will I need to order these?

logiktest · 09/03/2008, 11:26 PM

Home Cheapo, Blows, wherever. 3/4" SCH 40, TUBV aren't $15 there either. More like $4 or $5.

Angler02 · 09/03/2008, 11:28 PM

Well where do you shop for all your plumbing needs? I use this place cause its in the same plaza as my work. Makes for a fun lunch time!!

logiktest · 09/03/2008, 11:34 PM

Wholesale Plumbing (WP). It doesn't matter though. It's all the same BS.

The part. The schedule. The material, if you need to get picky. Price.

Angler02 · 09/03/2008, 11:36 PM

I'm not too picky I mean look at the people I associate myself with.
