Ok, Monday is a success! I had to take the pump apart to get the cast iron housing off, it's a good thing I never tried running the pump because uh, there was some debris from Saturday's repair in there. :O
Removal became much more difficult as mentioned earlier with the rust, no matter!
I got 3 of the 4 bolts off with that super rusty one looking a bit hourglass.
So, the fun part, getting the old flange off because I don't trust that to seal ever again.
This is the pump side, there still is a rubber gasket, but I could not remove it and you can see how thin it is around the 10-11 o'clock position.
Just the flange did not come off and that stupid elbow wasn't tight enough so it was spinning as I tried to get the flange apart. Joy of joys.
Ok, now I need to get a new flange, pipe nipple, elbow, and pipe nipple.
I ended up dressing in work clothes, driving in my work car to a local supply house and posing as if I was on a job when I went to buy the flanges, even said who I was with when asked. I could have gotten them from ebay for $10 less, but then had to wait for the parts to ship, I didn't want to wait to find out if I was wrong in parts again and plus, I need to get this off the checklist of shit. So, supply house had the flanges, I went to my chosen DIY store and got almost everything except for the 3 inch pipe nipple so, I had to go another store and buy a nipple.
Temporary pipe support, there is another pipe bracket out of shot.
Mimic almost prefectly except that one pipe nipple. It seems the installer custom made one as a 2 inch nipple from a store was too small, and 3 inch is what you see here. Ok, so what? There's enough movement in the pipe this won't pose a problem.
Installed! Checked for leaks, found none. woo!
So now the fun part of refilling the system of water and running things to get the air out. All the bleeders are lower than the baseboard radiators because logic. In that case I stuck with keeping the fill valve open, monitoring the pressure gauge on the boiler, and making sure the pump doesn't cavitate. It did a little, but opening the drain valve above the pump helped bleed off the air. Now because this pump is controlled by the boiler controls you see behind the pump, I had to set the thermostat upstairs to something high above room temp to get things to run. Not a big deal except for warming up the house an already hot day. I've run this for about 15 minutes before calling it to avoid overheating the house. I will revist this in a day or so.
Keen viewers will note that the pump looks all nice and shiny. I replaced it because.... I don't know, seemed like a good idea because the mounting parts are nice and clean meaning I won't have to worry about leaks. All in all, project done.
