05-05 Molded lavatories without CSA approval

Question: 05-05Code Section: 7Date:OBC 2006 Reference:

Question: More often we are seeing molded lavatories without CSA approvals on them and without overflows (see pictures attached). of the code says that if a lav does not have an overflow it must have a “center waste outlet fitting”.  Wholesale suppliers vary in the description of a center waste outlet fitting.

1. Please explain or describe what a “center waste outlet fitting” looks like.
2. Is a pop up plug or rubber plug allowed on the lav?
3. Is this accepted by other inspectors?

Interpretation: (On. Reg. 403/97) 1. The best way to describe a centre waste outlet fitting is to call it a c.o. plug and it looks exactly like a lavatory p.o. plug except that it does not have the holes required in the p.o. with waste and overflow. The concern with using a p.o. plug on a basin without an overflow is it would be an ideal place for bacteria growth. Please refer to the May 1998 June issue of the Bulletin on page 25 for the answer to a similar question.
2. The ones that we have seen have the rubber plug or tailpiece with clicker or grid strainer.
3. We will answer this question better once it is printed in the Bulletin and we receive tons of feedback, however, from the committee.  We have only one member’s answer so we will refrain from answering something that may or may not be going on in the province.
