Hey guys,

first off thank for all your advice thus far, it has been greatly appreciated. I have just purchased a new 400. It should be there within a week or two. I do have a question regarding the plumbing hook ups in the back...i see that it looks to be only 1 supply and return port, but they look to be about 1-1/2 ports to me....I am going to have 2 pumps hooked up(larger pump for house and smaller pump for shop). What is the best way to hook up the two pumps? Brass??? Black Pipe??? Copper??? i have considered them all and figured i would seek advice from owners whom may have experience on set-ups that have worked well for them.

Any advice, pics or suggestions would be helpful!!!

Thanks again!!

I’d hate to price out brass pipe fittings in that size.

Galvanized would work nicely, as long as you keep your water treated black pipe would work and is cheaper yet.

I would check the manual. I have seen other brands with 409SS that required the first fitting on the boiler to be brass.

You should not use copper.

Really? First one brass then whatever after that? A brass 1 1/2” tee would have to make ones nether regions pucker up.

yes the manual syas that the fitting into the stove has to be brass....i priced out gong all brass and also going brass to copper....its about the same. I guess if i want it done right the first tim going to have to just spend the $$$$$$$$$$$$$$$$ LOL

You can get 1-1/2" brass tees from ebay for around $12.

Really? How good are they? Local hardware store carries brass fittings made in the gold ole USA, very salty to say the least.

I have no idea how good they are.

Who cares about copper, look at all the $$$ in pumps you have hanging on the wall  .  I heat 4000sf of inslab and only have 1 pump, so by my count you have a WICKED huge house, or are doing SNOWMELT

No snowmelt and only about 2800 feet but the customer is young, this is his fifth and personal home, he wants total control of his heating, master bedroom at  maybe 55 and master bath at 70 and all with radiant Ultra Fin

That was my first guess with the lack of a tempering valve(s) in the picture.

Large ranch style house I take it?

Actually it's a cape with additions on both ends with a daylight basement on one end, both new ends have radiant in slab, I still need to add one more mixing valve, we will be back on site toward the end of this week.
