Can PP manholes be pre-installed in the side walls of the pool? Manholes similar to those on storage tanks? How should it be sealed?

This is quite rare; maintaining it must be difficult. I’ll help you transfer it to the water treatment section to take a look

I’ve seen manholes that can be pre-installed; as for how to seal them, I’ll wait for a reply from experienced marine experts

I’ve seen pool side walls with manholes, which are sealed using blind flanges and gaskets, fastened with screws. . . However, it wasn’t buried; it was on the ground. . . I asked the master, and he said it’s for maintenance purposes. . .

I haven’t seen it, but in theory it’s possible; the sealing method just needs to be similar to that of a storage tank. But the corrosion issue must be considered.

It is possible. When, due to constraints, it is not feasible to install a manhole on the top of the indoor pool and it must be installed on the side wall, it should be positioned such that its lowest point is above the overflow level.

It’s completely possible; generally, interfaces are built in during the design phase to accommodate future use.

I’m here for maintenance, is that okay?
