When I run water in my kitchen sink,it backs up in the basement

When you flush the toilet does this back up as well..? IF you flush the toilet and it also backs up in the floor drain, then your main drain is clogged and you will need to rent a large snake or call your plumber to snake the drain out for you.

If it does not back up when the toilet is flushed then you will need to find where the kitchen sinkk drain pipe enters into the basement floor... follow this pipe which will hopefully lead you to a cleanout... if no cleanout available then you could always try to snake through the floor drain, but it is tricky to do (because of the trap shape... hard on snake)... OR rent a pneumatic tool such as the kinetic ram (by General snake company) from a rental store... Here, you would pump up the kinetic ram to say 40 to 60psi (start easy)... or so... push into floor drain (remove cover if present) and "shoot" the drain line. Hopefully that will do it for you... but nothing beats snaking the drain line
Good luck!! Please let me know if this was helpful by rating my answer. Thank you.
