    Hello, I have had a problem with my heater for a few days ... When it is burning in the stove and the heater is warm, the water does not drip, and when it is not burning in the stove, the defect is dripping from the heater: / I would like to deal with this problem myself, therefore I am asking you for help :)

    If it is dripping as seen from the threaded connection, first try to tighten the nut, if it does not help replacing the gasket.

    If it is leaking on the pex, i.e. with a warm installation, the material expands and does not leak, when it cools down, it starts to leak, I think that just tightening will do nothing, you will probably need to replace the gasket or connector.

    How can I get to this gasket? And if I unscrew the screw from which it is dripping, will water come from the pipe?

    It will be pouring down rapidly !!! You need to close the riser (supply and return). Without closing the lift valves, you can only try to tighten this nut or unscrew it a little (for venting), but to check whether the gasket is replaced (if any) you must close the riser and drain the water.

    Take the wrench and tighten it. Even a properly assembled PeX likes to leak over time.

    It means that something is not correct ... A properly chamfered pipe + a good quality fitting cannot leak even at a much higher pressure than it is in CO.
    Probably damaged (when inserting the pipe) are the mini o-rings on the stub of the pex connector.

Topic summary

The discussion revolves around a radiator valve leaking water when the heating system is off. Users suggest tightening the nut at the threaded connection or replacing the gasket if tightening does not resolve the issue. It is noted that leaks may occur due to thermal expansion of materials, and if the leak is from a PEX connection, the gasket or connector may need replacement. Caution is advised when unscrewing components, as water will pour out rapidly unless the riser valves are closed. Proper assembly and quality fittings are emphasized to prevent leaks.
