Capped radiator pipe not drawing heat?
We are having our kitchen renovated in our condo and one of the construction workers made a BIG mistake. A radiator pipe that was sticking up above the floor (with no radiator attached) was meant to be cut below the level of the floor, capped, and new flooring laid over it as we didn’t need the radiator in our small kitchen. One of the guys did not cap it, laid flooring over it, and the first time our radiators kicked on since we’ve moved in steam was released through the floors and up in to the walls causing some damage to hardwood floors and our downstairs neighbor’s ceiling. When we realized the pipe wasn’t capped, the flooring was pulled up and it was capped correctly. To test the cap, the building engineer turned the boiler on to manual so that all the radiators kicked on in the building. The mystery of this story is that the radiator pipe we thought caused all the damage did not get hot or even warm to the touch. Is there any scenario where once a single radiator pipe is capped it doesn’t still draw heat? We are now afraid that there is another pipe somewhere that is causing the problem.
