Re: Venting - What's code?

So if the house requires a 3" sewer leaving the building ...

Here, the minimum size sewer is 4".

I once installed a drain from a sink in the garage and used 2" cast iron pipe to run twenty feet to the sewer. The inspector made me change it to 4".

The weight of the water in the pigtail has no effect on the gauge reading if the gauge is above the boiler tapping

It certainly did on mine.
So much I stopped using one on the actual gauge I use. In fact if it kept skewing a 3 psi gauge I imagine it would destroy a 2" magnehelic.

Or at least make it totally useless.

If you have the house plan, send it to one of the tubing manufacturers for a heat load and design. They may send it along to a wholesaler or rep for the area.

Have them do an cooling load also.

Don't consider radiant without a proper design.

Asheville area by chance? There are knowledgable wholesalers and hydronic/ steam guys down there.

Rehau, Uponor, Viega, Mr Pex, Watts, for pex brands. Their website would tell how to submit house plans to get a design done.

I see a company Radiantec https://www.radiantec.com/ they seem to sell DIY kits etc. Have you ever heard of them?

We've heard of them... usually from folks wondering how to fix the problems.

Re: Old Boiler Dating

Dating old boilers? I would definitely consider dating younger boilers. Sure, they won't last nearly as long. But maintenance should be much easier. Only the grey haired, mature gentlemen, have the necessary know how to maintain those old girls.
