The basement shower drains very very slowly. The same plumber has come 3 times now to vacuum, add a product, and use a snake over the past 4 weeks. But, after using the shower 2-3 times, the problem happens again, it drains really slowly.
I’m looking for another plumber who can fix the problem once and for all. How do you provide the free estimate? Would you be able to come see the problem before you provide an estimate?
Thank you in advance.
