Re: Does the BFPV look like it needs replacing?
The fiber washers are seeping, it would be best to replace them. Send me your address and I will send a couple, use the private message function if you want, or bob.rohr@caleffi.com
We have changed the design to use o-ring seals now on that and many other product

Re: Ball Valves
This is very useful information, thanks.FilthyTeaSnob said:To that end I have exclusively used their 77-140-10 series valves. They have a naming key that's rather long and confusing but the 77 series (not 77c or 77AR) is the no-expense-spared, we didn't cut corners on cost, valve I use. I personally try and get the 316 stainless ball, stem an d handle as it never rots (other than the plastic handle cover).
Re: Radiant heat of steam boiler
Speaking as a layman/homeowner/coal stoker boiler owner;
A single drop of water used to create wet steam expands 1,700 times.
A single or double drop header will create dry steam faster and deliver
heat to the radiators faster to heat them faster which will release the heat more
slowly.
The dry steam will send this heat into the radiators more quickly as it has
little if any condensate in the dry steam and they will shed heat back into
the living space for a longer period.
If your beautiful steam boiler does not have a great deal of
water in the steam chest it may not be at all possible to feed enough
hot water to heat the floor.
The other issue is if the steam boiler has enough water in the
steam chest would cycle more often and consume more fuel
if the slab is not adequately insulated also.
A steam licensed plumber and or a system design office of a
larger plumbing firm would have to look at your heating system
and the pex size in the floor and tell you if steam radiators would
be a better method of heating your basement instead of in floor pex.
You have to remember that every time you pull water out of the
steam chest to heat the floor you are lowering the water temperature
in the steam chest and the thermocouple will sense this and fire the
boiler.
Using small cast panel radiators would be a much easier way to add heat
into your basement by branching off the riser pipe to the upper floors.
If you have a one pipe system:
If you do not already have a single drop or double drop header in your heating system
adding a drop header or double drop header and the cast panel radiators would
heat your basement and increase your boilers efficiency.
I believe A 2 pipe system would require much more plumbing and pipe and any radiator
would have to be hung near the ceiling to allow for adequate drainage back to the
boilers condensate return tapping but I am not sure of this.

The last word about c-wire thermostats and wiring diagrams.
Not that I actually believe this wiring diagram will eliminate all questions about the topic but this should make it fairly simple to do for the next guy. Or girl.

Re: 3/4 copper to male slip adapter
I sweat both adapters to the tube, screwed it into the tank, then cut the tube to lengthEBEBRATT-Ed said:Nice trick. Did you just use the slip adapter to wrench the other adapter in and then sweat onto the copper sticking out? Or did you cut the outside copper off and thread something on to the slip adapter? I used to drill out compression x male adapters so the 3/8" OD or 1/2" od copper tubing would slide through to the bottom of an oil tank and tighten the compression adapter into a bushing on top of the tank.
Basically making a place to attach a wrench without damaging the copper

3/4 copper to male slip adapter
Working on the solar tank today. I needed a 10” brass nipple to make a clean connection
I drilled out a 3/4 adapter with a 7/8 holesaw, soldered it onto a piece of L copper
1-1/8 box fit perfectly

Re: Replumbing: Solder or Threads for Ball Valves
Another pro tip I would not have thought of.Mad Dog_2 said:Slip coupling...just make sure you mark pipes so that the couple is equidistant on each side. Mad Dog 🐕
Re: Ball Valves
Yeah, @Mad Dog_2 I settled for the International just for one 1/2" because I was tired of shopping, but got USA for the 3/4" s. This discussion will be a big help in the future because there are so many manufacturers but now I know what to go for right off the bat.
Re: Old steam system, New to me
Let the fun begin, finally started tackling this today. I thought the demo was going to be more of a pain in the ****, but getting the old copper fittings out wasn't too difficult. Couldn't break them loose so I had to cut a small section out and then screw driver and hammer the rest of the way.
I mocked it up and realized I still need a couple different size nipples that I don't have and another length of 3" for the front section.

Re: Thanks for everyone's help, it's finally installed
the dirtmag is most important for protecting the circulator which has a permanent magnet in the wet rotor motor which will attract iron particles from the system in to the rotor and bearings.
