Title: Display Knowledge Of Drain Access Points US1115
Post by: Michael Corleone on January 09, 2017, 05:11:42 PM

Just came back to me 'non competent' because of question J: Explain the purpose of a cast lid on an access chamber.

My answer: The purpose of a cast lid on an access chamber is to provide an access point into the chamber which can seal the access chamber closed and can be re-opened when necessary.

The marker noted to refer to page 276 in drainlaying essential skills book that covers lids but I have spent hours reading through that whole section ( installing chambers)  and the 'access chambers' book to find anything remotely connected to 'cast' lids.
A 'cast' lid could possibly be referring to a pre-cast lid or a cast iron lid?

Anyone able to help out with this?
