|In response to Re: Cast iron sewer pipe|
Wet venting is only allowed for fixtures on the same level, in most cases. Having the sink wet vented by the upper floors can subject it to a positive pressure when the upper sink drains. It should have a vent.
: : : Thanks for the replies. I was trying to decide whether to try this my self or hire it out. Since the sewer line is inside and certain tools and codes reqiurements are needed, I will probally get an estimate.
: You can use no hub clamps which have a continuous steel body around the rubber gasket. The san tee should be roughed in between 6" and 18" above the floor. I cut out as much cast iron as possible (7') and replace with plastic. You do not need an additional vent for the washing machine trap arm which is wet vented by the sink drain. You will probably need to have the cast iron line cleaned for it to take the faster dump from a washing machine. This is usually a $150.00 to $250.00 not including the drain cleaning. Add another $150.00 for the water hookups.LonnythePlumber
