Re: When to NOT use sharkbite? A question
Sharkbite is the easiest type of connect to disconnect, the only thing that comes close is threaded brass. So I like them for places that are likely to be disconnected.
Sillcocks fail all the time. If you get one with a copper sweat or PEX-B connection the pipe tail will be smaller than the body of the valve and will easily go into any hole that the valve fits in. If you put a Sharkbite as the first fitting on the inside of the wall it becomes a five minute job to switch it out.
The kicker is that almost certainly the replacement sillcock is going to have slightly different dimensions than the one that was in there. With a Sharkbite all you have to do is adjust the length of the tail piece of PEX or copper. You can even cut it long, attach it, measure on the outside how much too long it is, then disconnect it and trim to length. Easy-peasy.
If the inside of the sillcock is exposed I like to have a Sharkbite quarter turn shutoff valve as the first fitting inside the wall.
Re: Confused - Hydronic air handler VS heat pump VS heat pump plus furnance
Did you install a furnace and ductwork in a location that could still flood?
If the house was raised 8', I would assume that was decided to get it above the highest expected flood level, no?

Re: DHW Check valves
Swing checks sometimes get used as an over-heat protection valve on wood boilers. In this example the check is intended to stop reverse thermosiphoning.
Also if power goes out the hotter, higher buoyancy water will crack open the swing check enough to allow thermosiphoning. Same concept as a gravity hydronic heating system, movement caused by ∆T
So a swing check on an application with a thermal differential, may in fact not be checking.
Not an easy thing to calculate when a swing check cannot do it's job, really. A swing check really likes to see higher pressure on the downstream side to close and seal. A sewage lift pump is a good application for a swing check. High flow rate, can handle small solids.
If positive, bubble free check protection is what you want or need, go with a spring assist type check.
So that is why you want to know specifically what the check is expected to do.

Re: DHW Check valves
Hi, Old trick was to drill a small hole through the disc to allow slow gravity flow, and just be happy. The amount of leakage through it on a hot water draw is not noticeable. But @Alan (California Radiant) Forbes , you have too many people relying on you, so you have to live forever, even if not with absolute efficiency. 😇

I have flipped Tristands over trying to get 3 & 4 inch fittings apart. Unless you have another two pound plus helper to stand on the Tristand, you're dying . Mad Dog
Re: Is a bridge valve enough or do I need recirculating pump?
if you don’t have a dedicated return line from the farthest fixture, you can put a valve that connects the hot and cold under the sink. Then the hot recirculates back through the cold line.
Is that the bridge valve you are talking about?
It does require a pump. The pump could be on a timer, a motion detection, or a door switch. No need to run it 24/7

Just so we all understand what was going on…was that some kind of AI bot trying to "learn" how to install a toilet?

Have you ever wondered how steam gets to the radiator, this weeks video
Unlike any other heating system, steam uses no mechanic distribution ie pump, compressor, blower, to send heat around a building. I hope you enjoy this weeks video.
