copper pipe and vibration
Hi all;
I have a 50 year old copper pipe embedded in cement hydronic system and I have never seen
an answer to my question. Would the vibration from a washer or dryer (sitting on hydronic floor system) affect my old pipes? So far I only have to make up water once every 9-12 months and very little at that. I am new to this type of heat (always had forced air) and several plumbers said not to worry your pipes will fail from corrosion before they fail from vibration.
Nice to know…but does anyone have an opinion? I'm probably overcautious but I hate to put ANY unnecesary stress on my copper hydronic system if I dont have to. I checked prior posts but could not find any on this subject. Thanks in advance from a newbie!
Re: KBR 42 3 Bosch Greenstar
it's the first thing that comes up googling that error code, no flame detected on ignition. For any failed ignition on modern condensing boilers the procedure is relatively the same. Clean and check burner/heat exchanger, clean/replace electrodes, check gas supply and combustion analysis to correct any underlying issues. Fouled electrodes are typically a symptom not a cause!.
Once the new parts are installed and heat exchanger cleaned I would want to set up the burner properly. gas pressure, gas valve adjustment, check for flue recirc etc. those parts will foul up over time, but in my opinion if its happening before the 5 year point I would be looking into why.

FWIW, my go to electrician (a master of his trade), told me that significant voltage reductions are common during high demand periods, and that there is often significant equipment damage. This is in the queens and Nassau County area. New York. He obviously has no ax to grind. Presumably, electrification is good for the electricians.

To All, you do not need documents to know that an 8 percent reduction will cause AC units and other equipment to to fail. Ask the people in my community. Just think about it. If you have a normal reduction in voltage that occurs during the summer, lets say just 4 volts, then you add a reduction of 8 percent, which is about 9 volts. What do you have?

To All, there is something you should know about Electric utilities that engineers know. When the utilities do a 8% power reduction, they do it not for you. They do it so that the compressors in your AC units will not work. Only the fans will come on. Reducing load to sections of the grid. This will protect their equipment and prevent overloads and automatic disconnection. The utilities have a short time [less than a second] to correct an overload or a shift in frequency caused by high loading. I have gotten around this by using an AVR automatic voltage regulator. When I replace my burner this fall, I will connect one to it.

They are out of their minds. The grid is borderline as it is . More electrical load without improving the grid is just nuts.
From my experience when you get down around 108ish volts things stop working. Voltage is suppose to be within 10% of the equipment name plate. 120v which most things are rated at-10%=108
Re: adjusting airflow on Trane Gas Furnace
Thanks for all the responses. After much digging I was able to find the directions at tranesupply.com. All airflow adjustments are made through the interface on the furnace. I was able to increase the airflow and that appears to have resolved the issue.
Take care

Can you help identify my B&G boiler pump? Possible replacement? Repair parts?
My home in Seattle is 95 years old with the original hydronic heating system. Built in 1931 as a gravity fed system, it was modified in the early 50’s (estimated) to add a circulation pump when a second floor living space was added. That pump has been working for approximately 75 years and I am concerned about how much longer it will function.
I was wondering if anyone could help me identify what model of pump it is and if it is still possible to get repair parts for it.
If it is too old to continue to maintain, would you have an idea of what kind of modern pump could replace it?
The system has been operating well, heating the house for the 45 years that I have been living here. There are no issues with water circulation. A couple of years ago it threw a spring on the coupler and I was able to find a “common” replacement (Bell & Gossett 118705), but still haven’t identified the pump’s actual model number.
I really like this web site. Any help would be greatly appreciated. Thanks much! —Tom

check your local building authority website for reference material and mandatory inspections.
What’s the purpose of a micro-studio? It may bring up additional requirements.

Building a MicroStudio with my spare room.... Maybe
Hi all,
I’ve got an empty bedroom that’s been sitting unused, and I’m planning to convert it into a private micro-studio by closing off the interior door and adding an exterior entrance. This room shares a wall with my existing bathroom, so I’m looking into adding a small shower, sink, and toilet along that shared wall.
I’ve handled plenty of DIY work over the years—everything from toilets and tile to drywall and flooring—so most of the construction is well within my skill set. That said, I’d love input on key considerations for a project like this, especially around plumbing layout and drainage, since that’s the only piece I haven’t tackled on this scale.
The good news: all the plumbing is already along the shared wall, and I’ll be doing the majority—if not all—of the work myself. Just looking for advice on potential challenges or things to plan for before I dive in.
