    I have a leak at my reciculation pump of my oil fired hot water furnace. I was wondering what's involved in fixing this...or is this a job for a oil burner machanic?

    I've attached some pictures.

    You don't have any isolation valves. Hire a professional and have valves installed. Without valves the system has to drain, repaired, refilled and air taken out.

    Hi Sparky:
    Isolation valves would make life easier but there is a gasket in that joint that has failed. Drain the wate down, unbolt the pump, clean the surfaces, put permatex on both surfaces, put in a new gasket and bolt her back up. Now fill with water and bleed off all air; you know the air is gone when you can't hear water splashing and running in the system. I loved the hot water system we had in our house but it loved gas too much. I now use a geo-thermal unit.
