Amazing.. Was called to a PA plant as they wanted to shut down heat exchangers to change gaskets on piping. All stainless. Engineers came out and just started closing valves everywhere and yes water was still running through the loop off the exchangers..

I was like wait... LOL. No one seemed to know where the main shut off was. I traced the main to a wall but there where two large garage doors there. A code key to get in main door, but I just started pulling the chain to open the main garage door..

This is what I found...LOL

Now my problem and task at hand.

They circulate 180f water for liquifying sugar. They have hose reel stations for cleaning the floors and such but the water is 180F. They want 120F or so...( Someone got burnt).....

Im looking into what mixing valves to purchase. They are 1" hot lines to the hose reels. I am going to tap off of the eye wash stations for the cold. They want copper.

I figure I can get 1" mixers but run 3/4" cold to them. Not sure.

I am debating buying this too... $3000... Or just sweat them....

Buy the tool. Their page says
Built to Impress
, so impress us.

I can't imagine buying all the jaws needed to make this thing work. Could you justify it?

Doesn't that plant have Engineers and Maintenance staff? They damn sure better!

So someone got burnt... are they sure that the 120F water is going to be sufficient for the sanitizing task that I'm sure that hot water is meant to do?

It sounds to me as if that place is somewhat (more than somewhat) poorly managed.

Tell us what they produce so I don't buy it.
(I know you can't do that though...)

Geeze they only use hot water. When I worked for Bordens we used steam and cold water hoses to clean. If you weren't careful the steam would get ahead of the cold water so you had to be very careful adjusting the valves. (The use of steam dated back to when Purepack milk cartons were coated with wax not plastic.)

Yes many from what I saw. But it seems no on has a clue/ The piping in the plant is a calamity I can tell you and you can only guess what each pipe does... Lack of labels and valves...


So someone got burnt... are they sure that the 120F water is going to be sufficient for the sanitizing task that I'm sure that hot water is meant to do?
Its 180f for the plant. the hose reels were ran off the 180f line. The hose reels are for spraying the tanker trucks down and the floor grates in the floor to waste water evaporator.

It sounds to me as if that place is somewhat (more than somewhat) poorly managed.
Yes all chiefs and no Indians from what I saw... IMO a time bomb waiting to happen...

Well its a plant to liquify sugar for common beverages


My main issue is to get mixers to the 12 hose reels... I will be there several weeks I think...

I did tie into a eye wash for a pump lubrication a few weeks ago there. I am learning the plant slowly. This pump needed no more then 30 psi or the seals would blow.

Also needs a 1/4 gallon per minute minimum....LOL


In PA its hard to find competent parts supply stores belive it or not... I managed to find a PRV 25-75 psi and cranked it all the way out... managed to get 12 psi and added a gauge....

This is, do what engineers want type of work...

Notice copper to steel... Hey I only tapped into the 1 1/4 line....he he...

I think I did what they wanted and got an..." Ata boy"....

Yellow pipe is eye wash station and shower...................

Im reasonable $75 an hour T and M.....
Very fair for good work. Usually, once you get your foot in the door you're set for life. If they don't have an actual "in house" guy that they can go to then it could become you.

There are lots of "engineers" running around but that is not helping them. They need a "go to" guy that knows his sh_t..... and the building.

Pro press... Old fashioned??/

Well I got a few mixers in...

But... I was asked to tie in a new compressor and dryer to the main 4 tank system... Hmmm...

Used a fellow contractors pro press... Not sold on it IMO...
Looks nice and all.. Labor saver? Dont know yet.

Unit was heavy. My arms hurt...

Overall was easy but you need to leave distance between pipe fittings. If you press and make a mistake you cant just unsweat the pipe. You need to remove it all back to the pipe with at least 5" or so so you can press a new fitting on......

Ugg the kids today... soon they will not even be able to solder IMO...

Anyone have any comments on the pro press system before I drop $1500 to $3000 for a system with all the heads????


Uggg Im getting old.....

To think I poured lead 30 years ago .....

Pro press $3000 K..

Nice clean work.

A friend of mine has that press tool and all the jaws. He swears by it.

If I were doing compressed air work with copper I would want the ProPress. I have some vague recollection that copper and compressed air needs to be silver soldered to meet codes.

Thats all I use is 95-5 solder.

Solder joints are rated at 400 psi @ 100 F for say 2" pipe..

Pro press states 200 psi all around..

Amazing is they have 316 SS pro press fittings, and now..... pro press for black pipe.....

How weird. Never heard of this before (Why would I? I'm not a plumber.) And then 2 hrs after reading, I'm watching TOH and he used one to run a line for a NG grille. Just some odd coinkydink I know...

WOW! And you're only charging $75? You're working for nearly nothing in their eye's.

What surprises me is that I thought PA was very stringent in their codes and inspections. I'm surprised they're getting away with some of those set ups.

Commercial plumbers here run about $100+/hr

I see a lot of commercial plumbers and HVAC guys using the pro press tool. Its fast and a problem solver in some spaces, if you can choke down the initial cost. Then there is the cost of the fittings. Not sure if it is a good buy if you do not use it in residential. If you can, then it might be worth it.
