We've had a drain inspection for the house we've just moved into, which has identified a large amount of fat in the drains.
This is obviously due to people putting fat from frying pans down the kitchen sink like wot they didn't orter.
Now - we can put fat from the pan, or old olive oyl, into a jar and bin that when full. But there is bound to be some small amount left in the pans etc. Does it suffice to just be sure this is well mixed with detergent? The drain man seemed to imply even fat emulsified in this way would separate out and congeal. Any thoughts?
