  • No Hub or Service Weight?

    I am bidding a commercial plumbing job in Massachusetts. The building is one story and on a slab. I will be installing five bathrooms in this pizza place/pub. I am seeking opinions on whether to install 4" service weight or no hub cast iron for the drains. Someone told me the Massachusetts plumbing code requires service weight, but I cannot find that in the code book. No hub would cost less. Any comments & suggestions would be welcomed. Their will be about 60ft of buried cast iron.

    I would think that only service weight/push gasket would be allowed underground

      It should say on the blueprint what to use.

        honestly, if you can convince them to use plastic on the underground, you'll be doing them a favor.

        has anyone seen what soda syrup does to cast iron

        plastic is a great material if properly installed. it stays cleaner and doesn't rot. you do need to be careful around commercial dish washing temperatures.

          Were there no specifications included with the plans? It's the owners/architect/engineers responsibility to specify what they want you to install.

            Not always. It sometimes falls on the tradesmen for "design to code".

            I myself have received commercial plans with only fixture placement.

            No P section. No legend. Nothing. It's on me to figure out material, DWV sizing, supply sizing etc.

                That sure was nice of you to provide those owners with all of that free expertise at no charge and at the same time leaving yourself wide open for a possible lawsuit by them down the road.

                  I can't tell if you're taking shots at me or not. Let's assume not.

                  For one, who says it's free?

                  Secondly, I'm not sure exactly how one is "wide open" to lawsuits when designing and working within their professional parameters, insurance, & business "veil of protection".

                  But I will say that anyone, ANYONE, can be sued under the right circumstances.

                  Even someone that just makes birdhouses.

                    No shot intended, didn't mean to come off that way if I did. More power to you if you're including a design fee in your bid price as spec writing is a commodity that shouldn't be given away free. As for the lawsuit part, all it takes is one minor error on your part as to what material to use and the cost of making it right falls squarely on your shoulders. With a written set of specs. to bid off of that wouldn't be the case as the blame would fall on others shoulders. Design/build can be a risky proposition sometimes.

                      We normally use service weight with gaskets under slab in new construction.
                      Its fast and you can reposition fittings with out taking it apart.you need to support each fitting and hub of pipe.
                      No- hub you must use underground approved clamps and in tight spots takes up less room than sv
                      PVC is not allowed unless it is on a dedicated bar or beauty salon line

                        Agreed. Written specs make it easier and another veil of protection to remove liability. Just not always that way though.

                        I like to think it makes me a better plumber in that I don't have to rely on a ME for everything.

                        Believe it or not, there are many "professional" tradesmen on site that if you didn't give them very detailed blueprints would just have to sit down because they were lost.

                        But then again, I sometimes get lost in the blueprints.
