ᐅ How to retrofit a water pipe into a concrete wall and seal it properly?

Hello,

I have an old small concrete slurry pit. A hole was drilled in it some time ago to allow rainwater to drain out. However, I now want to collect the rainwater in the pit and install a tap in the existing hole so I can release the water when needed. How can I best seal the water pipe with the tap? Unfortunately, I haven't found a suitable solution yet, so maybe you can help me.

Best regards,
Patrick

So you basically want a plug? What about having an emergency overflow? You should have one anyway. And if you ever want to clean the pit, you can pump it out then.

Yes, basically a plug with a tap 😉. There is also already an emergency overflow.
