Hi, Me and the hubby were unscrewing the nut the holds the thermostatic valve to the radiator and we think we have bent/broken it. It is the brass nut the sits between the copper pipe and the rest of the valve bit. It is sitting slanted and allowing water to drip out slowly. We can't get the nut off though. We are not sure how to go about fixing it, because it is not straight it is not making a perfect connection when screwed in. Any help would be greatly appreciated!!!
