Re: When to NOT use sharkbite? A question

Sharkbites are a temporary, emergency fix, but this is America...you do what you want except gas work or anything that could contaminate your local drinking water Supply..Don't worry, if it blows out it blows out.Only water Mad Dog

Re: Did Everyone Get The TT Recall Letter?

Yes…We received the letter

Yes…Although we did not Install ANY of these boilers we keep all the serial numbers for all the boilers in an Spread sheet.

Yes… We are contacting all the Customers with the affected Boilers to keep them safe as a responsible Contractor should do…😉

Re: When to NOT use sharkbite? A question

@JayPoorJay Shark bites are made for your situation. The homeowner do-it-your-selfer.

I have found them to be a great transition fitting and have used them myself from time to time.

Simply follow the directions on how to install them.

The first thing I would do is install a couple of valves on the hot and cold lines to isolate this area from the rest of the house. 🤔😉

Re: Oldest Boiler

My brother lives in an old apartment building in Oakland. The building has two-pipe steam. Not very well maintained of course.

From the 79's, it could be ceiling electric radiant too.

Any chance you took a pic of one of the stats?

Pretty good list. Plumbers should show it to their customers who complain about their rates.

Re: Replace B&G 100 or use Taco 007 monoflo

From what the OP says, it suggests approx. 8ft/hd and approx. 8 gpm. He may have been dancing near shutoff head for the 100. The 007 may work, but it's a little too close for my liking. I'd probably go with the 0010, and put a globe valve on the return, to dial the flow in. That's my unprofessional opinion.

Re: Replace B&G 100 or use Taco 007 monoflo

The 007 isn't the best direct replacement for a B&G 100 in terms of flow rates, though it may be the best match for your system.
The 0010's curve is closest to the 100 and even exceeds flow just a bit. It may be overkill. I really can't tell from here, but these are the specs.

Re: Air in boiler feed water

One trick is to raise the boiler temperature, maybe 180 for a few hours. And also raise the fill pressure as high as possible for the same period. Boosting the system pressure basically squeezes the bubbles small and it may be enough to flush them through.

At some point the system should get to a 100% air free condition, and stay that way for years. Unless air, or fill water with air in it is being introduced.

P/S can make it harder to get all the air out. Indirect tanks sometimes suffer the same issue, the coils never flush 100% clear.

The tanks with large coils 1-1/2" for example the flow velocity can be so slow it doesn't move air with the water to the vent locations.

Purge valves are fill and start devices, you should not need to use them on a regular basis. As you do, you bring in O2 laden water.

Playing with this small piping demo. I can pump a full cylinder of air into maybe 3 gallons of water content and within minutes all the air is eliminated. At room temperature! There is no question to the 97% efficiency of microbubble air separators.

I have been building and demonstrating air elimination hands on displays for maybe 20 years now. They are always a crowd pleaser when teaching hydronic techs.
