    Here's my problem. Customer bought shower base (Mustee) with 1 1/2" drain. My plumber told me Massachusetts code is 2". The base was bought at Home Crapo (never again) by my customer. I then called Mustee and was told there might be a waiver # for Massachusetts but he's not sure. Never heard back from him. I then went to the (assistant) plumbing inspector and told him about it. He told me to talk to the lead inspector in the morning and that maybe he will come out and look at it and possible approve it. I went through alot on this because the building is on a slab and I cut open the concrete to replace the 1 1/2" galvanized pipe with 2". It's about a 4' section of pipe. It went well because the flange had a 2" bushing that reduced to 1 1/2" but i am going to be ripping if i cut the floor to only get approved by the inspector with only 1 1/2" piping. I just don't understand why they would make me change to 2" but yet allow a 1 1/2" drain. I do have a 2" shower base available. Anyone have any thought's or opinions on this I would appreciate any input. Thank's

    The first thing that comes to my mind is to I see about returning the unit and exchanging it for one that has a 2" drain opening. HD is usually very good about exchanges, and in this case at least, they sold something that does not conform to code. That would be a pretty strong argument if push came to shove. If that doesn't work, then I wonder if it would be possible to enlarge to hole to 2". In the real world, an 1-1/2" drain will probably drain the shower quite nicely, but one should stay within code.
  3. take it back to home --do do

    jsut like GARY said...

    its only about a $125 base if that....


    Simply Blame the inspector if you must............

    then tell the cheap ass customer it wont work

    and the inspector WONT LET YOU USE IT

    Tell the tight wad to tangle with the inspector

    ON HIS TIME if he still wants to use it,,,


    Also, claim your plumber will charge him extra for his
    pain and suffering if this base becomes a major problem...


    that is within your rights to do too
    if that $100 base kills the plumbers day.

    base

    Lasco does a lot of weird things, such as make the floor of the base an inch higher than the apron so that it can never be set directly on the floor. I guess, given that, that their engineers might also decide to make a base with a 1 1/2" drain that might not be legal in any jurisdiction. I would not install it and would insist that the customer return it. YOU are the one he will be complaining to, and about, when it does not drain properly.

    im under the impression any dwv in a slab must be at least 2".
  6. total distance with 2" or 1 1/2", that is what is important

    It is not about a single constriction. The total length of the run is the important thing.

    How about running the line and trap 2" then bushing it to 1" 1/2" from the trap up ? Then you are allowed at least 8' on your run for a vent. Also ,this is VERY often how tub waste & overflows are done in a slab .

    Just a thought ,,,instead of getting inspector & homeowner all riled (sp?) up.
