Hi,
there is an air vent on the stream riser pipe in my apt. The vent usually goes bad and starts producing loud noises (like banging with a hammer). That I assume happens because the pressure on the stream riser pipe can be quite high at times.
I don't even know why the air vent was placed there on the first place. There is just a whole drilled in the pipe and in this whole the vent is screwed in. I presume they placed the vent so that the stream rises faster.
Can I remove completely the vent and just place/screw a bolt where the air vent was? I am hoping that would remove the loud banging problems. Any suggestions?
TIA michalis
