Only problem with testing tanks is they fill them with water during the hydrotest process. If you ever intend to use them as reclaim tanks to hold refrigerant while servicing a system the tanks will...

I got my old Geo back, I built this system in 1981 for my new home. Gave up the home about 12 years ago in a divorce (right after replacing the compressor)

Got back the service rights a...

If you are saying the leaving water temp on the hydronic side is 185 you either have low circulation or the water is short circuiting the buffer tank and being returned directly to the inlet. 185...

At least it has Huricane Straps

Anyone remember the R12 to 134 conversion days? Recomendation was less than 2% of original mineral oil remaining and requiring mutiple oil changes to get it there. After a few years that number...

This one keeps the rain out

At what level did they hit water, if they hit water at 50 feet then 200 feet of your loop is in water (or very wet grout) and would transfer better than dry grout. If they never hit water then you...

I would worry about having 1 loop shorter than the others, water/glycol will take the path of least restance so the shorter loop may have a higher flow rate and starve the long loops. Someone smarter...

Wow, Have not seen 1 of those in 30 years. All the ones around here were owned by the Ice Cream Companys. If you bought their product they would install them to run your soda fountain and dip...

I always open liquid valve first

Think about a precharged unit that has been in storage for a few months, it may have some liquid refrigerant in the compressor sump. When you open the suction...

Just a question not knowing what refrigerant was involved and what the head pressure would be but is the crankcase rated for the discharge pressure?

With the suction valved off and the discharge...

On a VisionPro how many CPH do you set that second stage for.

Tryed that walking backwards thing with my parents once when I broke curfew and had a few to many, They did not fall for it.

The Ho Wah calls and says "Kenny, come quick. Air Crdishner sruck by rightning.

Wet rags around the soldered end should work fine. Only problem I could see is if you have even a drop of water still in the pipe you are going to make steam that has no place to go. If it builds any...

If you cannot go over 4ft how to you tie off, do they have a magic tie off point that just floats up above you??

If I am reading this correctly, why is R502 gone. It is rated lower than 12,22 and a bunch of others.

Had the same thing with a York, everything pointed to the roll out switch. Replaced it and it was locked out 24hrs later. Replaced the roll out switch again with a manual reset switch to test and it...

Looks good, the only thing I do not like is in the middle photo the back wall.

The 2 center lines straight thru the tee's will flow more that the outside lines that are on the side outlets of the...

I seem to remember 500 being a closer match to R12 than R22. Someone has got to have a stash of 12 if it just needs to be toped off

If the Dr. does not know I think I would pass on him for surgery

It's called a counterflow condensor. The hot vapor from the compressor enters at the water exit. The vapor is still hotter than the water so it transfers heat, as the vapor moves thru the condensor...

Be carefull with hardware store grade stainless bolts, I find them brittle and have had the heads break off with less than the required torque appled

Also try to clamp the flange togther in the area of the removed bolt with some vice grip welding clamps.

I know I am going to get jumped for saying this but in the R-12 days I would get the charge close then add or remove charge till the suction line frosted 4 or 5 inches outside the case with the box...
