Hi all,
I have been tasked with changing the sand on my dad's filter. I closed all the three valves (leaftrap intake, side intake and bottom intake.)
I set the multi-port valve to 'closed' and unplugged the power cable. When I unscrew to top lid, water gushes everywhere indefinitely. I don't know where it's drawing from and how it gets through the 'closed' multiport valve. After about 5 minutes I forced the lid back on and screwed it down again.
What am I doing wrong? Is this normal?
Opening the filter and water gushes out!

Have you tried setting the MPV to BYPASS which cuts out the filter

Provided it's not a top mount filter
