I don’t want to start another thread so maybe someone can help here:
Anyone have experience drilling a hole just below the water line using a Durso drain for an overflow return? Doing research I found a thread that said drilling a hole would relieve back pressure and allow it to drain without surging. I’m looking for any old timers to help. L9l. My overflows are old school but someone had to be able to make them run right.
