since as far back as i remember, no valve on expansion tank. Big no no and besides it's a waste of money. Alls you got to do is drain the pressure off to change the tank. Not a big deal for someone that knows what he's doing
Here's a good one for you all though. IPC 09 Code. All backflow devices with a vent (watts 9D) must be indirect piped to a drain. This includes soda fountain and drink dispensers with BFP's installed. Have fun with that one
here are the photos with vent but condensate water pump was not there at that time. http://www.flickr.com/photos/lmei007/ I rotated all photos before I upload to flickr but they are still like that. I have no idea why is that. sorry guys.
My plumber almost done my oil to gas conversion. one zone only and heating only. future zones and gas indirect water heater are considered in this project with some extra labour hours and parts cost to him. It looks good to me. How about your professional view?
The boiler is Burnham Alpine ALP105 gas boiler.
I asked him to fully follow the manufacture's layout recommendation except those optional parts (page 41 of this manual http://burnham.com/pdf/101602-01R5%20(web).pdf) but he still ignored one or two valves and tell me they are not necessary. These valves on the zone pump are added after my few minutes asking but at my extra cost.
After looking at the pitchers there are valves that need to be installed to isolate the pump and drain valves need to bee added, getting the air out of this system would be difficult at the least.
