There is a 2-3" hole in basement floor that has water in it with a perforated plastic cover over it. It must have backed up a bit as there is a dirty stain on the floor with a water stain. About 3' from that is a sewer drain cover that looks capped off. So should i be alarmed about the water and call a plumber or call the township if it is the sewer?
New build house that is 7 years old and never noticed this before today. Any advice would be great
A drain connected to the sewer (or a septic system) properly has a trap. You are probably seeing the water in the trap.
If you have never put water down that drain, for example when washing the floor, it is possible for a trap to dry out. It is also possible for the sewer to back up into homes emerging first out of floor drains. You can install a back flow preventer if there was none there already but you would have to dig through the conrete floor.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
