A thread on the tragic drowning on the Costa Del Sol. I have no info that’s not in the public domain, but I’ve seen a lot of speculation about the pool pumps etc, and as I know a fair bit about this subject, I thought it would be worth explaining a few things... Firstly, although drownings can be caused by too much suction in pool sump valves, it’s very rare because most pools are designed to ensure it can’t happen and the cases you do see, tend to be outside the EU and in much larger leisure pools. Not a small 25m (approx) pool.
