Replacing 40-year-old stuck tub drain

tub drainminnesota_nice_guy asks:

I’m trying to replace a 40 year old tub drain in a steel tub. The dumbell tool I have doesn’t fit down into the crosspiece to grip properly and every tool I’ve tried to get down into it to unscrew it has broken when I try to unscrew it.

I’m picking up a drain key which should help me get more leverage (and shouldn’t break). I’m assuming the fact that there is 40 year old putty hardened onto the drain is causing most of the issues. Any tips to working this out without breaking a pipe or causing damage would be greatly appreciated!

For extracting tub drains, Rectorseal manufactures a tool called the Golden Extractor. Using a standard 3/8” ratchet, the Golden Extractor is designed to grip the inside of the tub drain even when the cross arms are rusted or broken off. When turning the ratchet counter clockwise, the tool distributes equal pressure at three contact points of the drain making it easy to extract without any damage to the tub shoe. The Golden Extractor is also designed for installing new tub drains without scratching the new surface.

RectorSeal® Wins Product Design Award for AC Leak Freeze PRO

AC Leak Freeze® Pro with Magic Frost wins a silver Dealer Design Award sponsored by Air Conditioning Heating & Refrigeration News Magazine.

Houston–RectorSeal® LLC, a manufacturer of quality HVAC/R products, won a Silver product design award July 24 for its AC Leak Freeze® PRO with Magic Frost refrigerant leak sealant in the 14th annual Dealer Design Awards (DDA) Program’s “Components & Accessories” category. Sponsored by the weekly trade magazine Air Conditioning, Heating & Refrigeration News (ACHR News), AC Leak Freeze PRO with Magic Frost, was judged by an independent panel of HVAC contractors and competed with 80 other product design entries.

AC Leak Freeze PRO was introduced last January and is a quick, easy and safe applicator for applying RectorSeal’s renowned AC Leak Freeze refrigerant leak sealant into commercial and residential air conditioning and refrigeration systems. Unlike some disposable refrigerant leak sealant applicators, AC Leak Freeze Pro doesn’t require a labor-intensive R-410A system pump down and safely withstands all typical refrigerant pressures. The Magic Frost portion of the patent-pending AC Leak Freeze formula is a lubricant additive that extends compressor lifecycles.

Approved as an OEM product by many tool and compressor manufacturers, AC Leak Freeze Pro with Magic Frost is the HVAC/R industry’s safest formula for service technician and the refrigeration system. Its proven compatibility flows with the system refrigerant/oil to permanently seal small leaks and prevent them in the future. The AC Leak Freeze PRO with Magic Frost formula is not moisture activated, has a safer flashpoint rating than the competition, and doesn’t use or create polymers that can potentially clog compressors, recovery/evacuation units, Schrader valves, capillary tubes, TXV valves, micro channels or manifold gauges.

AC Leak Freeze PRO helps preserve the environment from refrigerant leaks. The Environmental Protection Agency (EPA) reports that emissions of HFC and PFC refrigerants were 149.9 million metric tons of carbon dioxide equivalent in 2015, a figure that doesn’t include the widely-used HCFC refrigerant R-22.

“These awards give us a unique opportunity to recognize the outstanding research and development efforts that go into many of the products serving the HVAC/R industry,” said Mike Murphy, publisher, ACHR News, which is distributed nationally to more than 33,000 members of the HVAC/R industry.

HVAC: Installing a ceiling unit. Is this against code?

Unless you oversized the rod that supported the sprinkler line, it may violate code.

Usually, plumbers (or any other trade) put the minimum required sized rod for their own hanger system. They don’t upsize unless it’s agreed upon before install.

I’ve been on a few jobs that I’ve actively gone to other trades and reworked the hanger systems.

For example – Our ductline took up the whole hallway. Engineered drawings stated HVAC elevation as ceiling down to 2′ below ceiling. The electrical elevation was just below that. For them to hang their cable tray, they would have to anchor outside the duct, and then span the whole hallway with unistrut. (their cable tray was about 16″ wide)

1- They would have to drop their threaded rod first down the length of the hallway as there was no “safe” way to get to the ceiling after the ductline was in. (And then I’d have to deal with their rods as I was installing)

2 – It’s a waste of unistrut to put up 6 feet worth to span the hallway for a 16″ cable tray.

3 – It’s a waste of threaded rod for them to drop from the ceiling (although it was probable bid on, hanging from the bottom of the ductline would save them 4′ of rod per hanger which equates to a higher profit for them.

4 – They would have to pull off another location to come and put in their anchors and rods which would have held up production for both us and them.

In the end, I made a deal with them that I would use their materials (upsized rod that would support both HVAC and Electrical tray AND their unistrut (which they would have used anyways to span the whole hallway) Saving the HVAC company the cost of rod and unistrut and saving the Electrical company the labour cost of installing their hanger system. – RWCheese
