I'm not picturing how this works.Can't drill either- I've seen some without the overflow box (hob)- but just plumbed
There's people here with way more knowledge than me on this let them tell you if this is a good solution or not. I do know that the hob I run is proven safe.One has a 2" pvc pipe with cuts for an overflow with a 1" inside, over the top with some elbows like a sink to keep water in the line- basic design makes sense to me- just need to check it out more
Why I asked- still a long way off for the tank- stand first lol- the idea intrigues me thoughThere's people here with way more knowledge than me on this let them tell you if this is a good solution or not. I do know that the hob I run is proven safe.
Educate me- in my mind a sump is fed by gravity and the size of the pipe determines the downward flow- the return pump has to equal that- so it doesn't matter if the tank is drilled or not- you just don't want to lose flow if there is a power outage
