Re: Prevent mold in mini-split heads
Everyone that is saying they see black mold in their units.
Are you 100% sure it's mold and not just caked on dust / dirt / oil from cooking etc? I'm asking because a white appliance that appears to have brown caked on dirt painted on might very well be mistaken for something growing in it.

Re: First time flushing hi-eff boiler-what do I need to know?
Looks like all you need is a flat-bladed screwdriver. And from that drop down screw, you have a Viessmann boiler.
Why do you want to flush your boiler? It should not be flushed unless there's air or a clog you want removed.
Re: NJ Boiler replacement decision points...
a follow-up, we're opting to go with a boiler with indirect tank. Except for the potential of a series of design days, the system should be able to provide more than double the FHR than our existing system despite a dip in space heating to accommodate should we need a high volume of hot water.
At some point, the house will benefit from increased attic insulation going from decrepit R13 to at least R30 with further air sealing. This should help mitigate some heat losses from dips in space heating output.
thanks all for the advice!
Re: Sloan Flushmate
should be dry. Water in tank is typically leaking plunger valve (#3 in IPB) on top of plastic tank.

Re: Can you help identify my B&G boiler pump? Possible replacement? Repair parts?
Looks like a 100 series. If the rubber bushings the motor is mounted in rot out it will misalign the shaft and start breaking couplings. Replace them when they get soft.
Is the system still set up as a gravity system, did anyone change any of the piping or the emitters? If it is not changed almost any circulator will work since it is designed to be gravity.
Re: header and main piping configuration
Best explanation is "Hay Boss! Do you want it right the first time, or would you like to go back several times over the next year or two, to solve banging, and uneven heat issues for free, while still paying us our wages?"
Re: Can you help identify my B&G boiler pump? Possible replacement? Repair parts?
That should be easy to replace. Personally, if I was worried, I would buy a replacement from a hydronics guy. I might keep it on a shelf, just in case , or I might replace it for improved efficiency and an oil free motor. Not so sure I would worry about it dying, but that is just me.
