Can the drain pipe of the balcony be wrapped in bricks

No, I don't have any observation holes now, so it's basically fine.

The toilet sewage inspection port can be sealed after the renovation is completed, and it must be sealed after the decoration is completed, for insurance. The toilet sewage inspection port is equipped with an openable inspection cover and is installed on the drainage riser and the long transverse pipe section for inspection and clearance. The inspection port is generally installed in the riser, for the connection between the riser and the transverse branch pipe when there is a foreign body blockage, and the drainage riser of multi-storey or high-rise buildings should be installed every other layer, and the spacing between the inspection ports is not more than 10m. >>>More

If the sewer pipe is best wrapped, you can also use other methods without bricks, you can play wooden keel or light steel keel and cement pressure plate on the wall: use the wooden keel to build a bracket, and then nail the cement pressure plate on it, and paste the tiles after plastering. There is also a gusset method, which refers to the method of using the ceiling gusset to directly make a frame to wrap the riser. >>>More

This one is okay, the power is very small, the heat is very small, and it can be wrapped.

It is recommended that you negotiate with the property management department, and if the negotiation does not work, then report to the property management department of the local housing authority.
