Tried to replace gasket to mpv, turned off pump, closed valves to skimmer, drain and vacuum.
Removed lid and water continues to flow out, rapidly filling up the pool box.
Have changed these before so am lost why there is still water flowing out, this is a new pool.
Obviously cannot carry out any future maintenance to mpv.

To do maintenance on the equipment pad (or box), all valves need to be closed that would allow water to flow in & out to the box. I can't tell from your picture, but there should be at least TWO valves, one before the pump (suction side) and one after the filter (pressure return side). If those two valves are closed, then no more water from the pool should get to the equipment. If you do not have a a valve after the filter before going back to the return jets, then I suspect you'll need to plug the return jet(s).
