Capped Riser

Lis Member Posts: 2
The steam heating riser in my bath was capped before the top floor. It is making lots of hissing noise and caused some damage to the ceiling. Is there anything that can be done to repair?

    it sounds as though the cap is leaking, possibly due to over-pressure. have your steam man check the pressure and reduce to under 2 psi MAX. reducing the pressure will reduce fuel cost as well [even more savings by further pressure reduction with a vaporstat].

    naturally, the cap should be reset with some new teflon tape.--nbc
