I plan to put in a sump and a pump in my cellar to protect against flooding. How can I cut through four inches of concrete to dig a sump?
There are concrete cutters out there who will do the job for $200 and up per cut. To do it yourself, I suggest you get an impact drill from a rental place. Make sure you get an extra long bit. Then make a series of holes along a line and chip out the remaining concrete. If you put the sump against a foundation wall, you will have to make three cuts. If you put the sump in a corner, you will need two cuts.
You might be able to rent a rotary saw with an abrasive blade for very slow cutting, but I don’t know how deep such a blade will go.
Wear a mask when cutting concrete. You do not want to breathe concrete dust.
Never miss a local story.
My toilet drains are very slow. I checked the label of a drain cleaner, and it said not to use it in a toilet. Why not, especially since the toilet drains are the slow ones?
I think it is because the lye type drain openers are caustic, and spilling any of this caustic substance into water, as in a toilet, would cause dangerous splashing. Drains with no water showing can be treated with the caustic opener. So instead of the caustic drain openers, use the enzyme types. They may be slower, but they can work wonders. Alternatively, clear the toilet drain with a snake, a wire augur that can remove some of the gunk that is narrowing the drains.
