Checking up on your RAV? Why don’t you ask him directly for Mekoros?
Yes That is the buzz, Even though I haven’t yet heard from a ???? ????? I have seen a sign to that effect at 16th Ave housewares, by whose authority I don’t know. I tried to do a search to see if I can find mekoros all I found was http://www.ohryosef.org/tevillas/tks001.htm with no mekoros I have no idea who this kollel is.
Neither the OU oukosher.org/index.php/common/article/a_tevilas_keilim_handbook/ or StarK http://www.star-k.org/cons-appr-tvilaskelim.htm
mention it. The email addresses are [email protected] [email protected]
An even better idea is try to find a copy of ????? ???? ??????
