No manhole is left in the sewer pipe.
If your home is not on the one floor, the possibility of sewer blockage is very small, so it is recommended not to leave a manhole.
Don't lay bricks at the manhole, cover the manhole with ceramic tiles, and then mark the manhole. In case the sewer is blocked in the future, use an angle grinder to cut the ceramic tiles for overhaul.
After the maintenance is completed, buy an aluminum alloy maintenance port and seal the hole.
