A few weeks ago our shower started to occasionally drain slowly. As it got worse, I thought I’d have to get out the snake or call a plumber. Then the other day I thought ‘why not just try the plunger?’
30 seconds of plunging, and I suddenly felt the blockage break loose, and the 8cm of standing water drained immediately.
Gotta love simple fixes that work.
Need to watch out for bellies in your runs to septic/sewer… that can slow down a lot of things too, especially if you don’t run a lot of water down it once or twice a week.
