Boiler repair

I have a residential boiler heating system....the problem is that the check valve is leaking....water is coming out in a pretty steady stream....the boiler is fairly old (20+ yrs)....it has an expansion tank with a diaphram....i dont know the brand of the boiler....the system seems to be heating just fine, but the water is leaking pretty consistently....any ideas?

I would suggest you get it repaired before the leak becomes a deluge.

Would be a good job for a heating contractor unless your into plumbing.

I read that it may be a problem with the expansion tank needing more air. Does this sound accurate?
What do you think is the problem.....I am able to do some plumbing repairs.....

Could you be referring to the pressure relief valve.

If you were then it is possible the pneumatic tank needs a charge of air.

The check valve will be on the water supply line and the relief will be on the boiler.

I just read that the water coming out of the check valve may be a result of not enough air in the expansion tank.......
Regardless, what would you say the problem is?

If water is coming out of the "CHECK VALVE" then it is leaking.

No, the expansion tank will not cause water to come out of the "CHECK VALVE".

Are you sure it is a "CHECK VALVE" that is leaking and not a "RELIEF VALVE".
