long snorkel to replace cover on main drain?

[CarlD]

Hi,

the cover has come off our main drain. It occurs to me that I either need to learn how to scuba dive or I need a very long snorkel (9 feet or so). Does such a thing exist?

tia,

9 feet underwater you won't be able to breath through a snorkle--the water pressure on your chest cavity will be too great. From what I understand, every underwater breathing apparatus requires a pressure regulator, so the pressure of the air you are breathing matches the water pressure around you.

Your alternative is to work in short 45 second units, coming up for air.
