@ October 29, 2013 2:28 PM in baseboard stays cold

If the system worked before you may have some air in system, any time work is done on hydronic systems air will get back in system after refilling,  are you bleeding at highest point and for how long, are you bleeding with pump off, do you have purge valves for zones

I have used a brass nipple before on smaller pipe


@ October 17, 2013 10:30 AM in high carbon monoxide level

describe in more detail the flue,  size/height  or include photos

look up petcock drain valve  online

shut off valves will allow isolation of individual radiators for any future repairs,  proper piping practice used by steamfitters for decades,  some balancing valves,circut setters are not 100% shutoff.   I worked in the Bay Area for 20 yrs,  If you dont already have a contractor call RMA   Redwood Mechanical or ABCO Mechanical

 Direct return      Make sure you install positive shut off valves on supply and return on each radiator as well as your balancing valve and drain and purge valves or air vents at high points,  these valves will help you when filling and draining system.  some prefer balancing valves on the return of the radiator,  ball valves not recommended for balancing, use a good quality balance valve that has gauge ports for installing a balance meter or gauges.   Bell&Gosset, Taco or Victaulic make good valves

wall furnace

@ October 13, 2013 12:52 PM in wall furnace flame recirculation

Call the company that supplies your gas    In a lot of areas they will check your heater free of charge,  and I always recommend a good CO detector in all rooms


@ October 13, 2013 10:17 AM in Really bad install

Is this boiler atmospheric, if so why barometric damper, it looks like the horizontal flue is not pitched upward     could just be the angle of the picture


@ October 11, 2013 10:22 AM in wall furnace flame recirculation

Does he mean flame roll-out which could be caused by a blocked, damaged or incorrectly installed flue, does the heater have a fan?  could the heat exchanger be cracked ?   which would require replacement of heater


@ October 11, 2013 10:11 AM in amtrol model 30expansion tank

diaphram or commercial bladder style tanks, always make sure the air charge is correct before allowing water into tank,  should match system press.


@ October 10, 2013 3:18 PM in broken cap on steam valves

 If you can find the same brand valve you can loosen the bonnet on the old valve, remove the disc and stem assy. and replace it with disc stem and handle  from new valve.  Or just replace the valve.    I  dont recommend this as a homeowner type job


@ October 8, 2013 10:20 AM in firetube vs. watertube boilers

can you be more specific on the boilers you are talking about


@ October 4, 2013 2:51 PM in HoneyWell 8043G Zone Valve Question

Use a honeywell R845A 1030 relay package


@ October 2, 2013 11:13 PM in Radiator Valves: Full Port?

All the supply houses I would deal with  (Cal Steam, Ferguson, Pace supply ) had no problem letting me take valves and fittings to a job as long as I returned them the next day     no restocking charge,  I am not in favor of import valves but sometimes the dimensions would fit a problem radiator job


@ October 2, 2013 10:22 AM in Radiator Valves: Full Port?

Hoffman or Hammond, used either or on 1 pipe steam for years,  dont get to hung up on this full port thing    get 1 of each brand and see how they match to your old rad.  return the 1 that you dont need.

dirty water

@ September 28, 2013 7:44 PM in Dirty Steam Water in Hot water tank

Do you have a backflow preventer on the boiler.  have you had water line repairs in the area


@ September 28, 2013 7:29 PM in Pneumatic controls

worked on them for yrs.  pneumatic contols were usually used in commercial applications  


@ September 26, 2013 9:53 AM in How to find a leak

Is'nt the condensate from the flue gas


@ September 25, 2013 9:53 PM in How to find a leak

Check the relief valve ,  some times hard to see if its leaking if its piped into another drain line


@ September 25, 2013 9:47 PM in ac system design help

available online  Bookmark Inc   1-800-642-1288, or check your local Trane supply house  $40.00,  well worth it


@ September 21, 2013 10:29 AM in Help: Leaking Drain Pipe On Side Of Furnace

I agree with all, you should also clean drain pan,  there are products available to put into the pan to lesson future clogging ( pan pills ).  Check the equip. install instruct. and see if this equip requires a trap
