It is not enough for a full drain.

This is what mine took with a filter r&r, I bought another 6 after buying 10 wanting to do a full flush & learning it was not possible.

I did 6, then months later another 3.5 which is what it released just from opening the drain leaving me with these 6.

The least I found these for after months of searching the net was 14.xx plus shipping.

I'll do 80 shipped USPS parcel post with tracking.

Thanks
