I have not posted in a while and I have many things to talk about. The detail work on my slab is close to being complete and I am getting things ready for the concrete truck.
In the state of MA, residents are just too stupid to glue pipes together. It’s possible that someone might be overcome by the smell of PVC glue and become injured somehow….its for the children…keep them safe!
Someone somewhere (probably a plumbers union) decided that only licensed professional plumbers are allowed to install pipes. This has led to a situation where plumbers just don’t give a shit. They cherry pick the jobs they want to do without returning phone calls for the other jobs offered them. Many quote extreme prices for small jobs hoping to gouge the shit out of unsuspecting consumers.
One plumber quoted me $7500 not including fixtures to plumb my little bodega. At first, I thought “maybe this is going to cost more than I thought”. Then I looked at his quote and he had listed “ABS drain pipe and fittings” at $675 just for the materials!
Being curious, I pulled out a tape and determined that it would require about 11 feet of 4 inch pipe, and 9 feet of smaller 1.5 to 3 inch pipe to complete the job. The job would require about 10 fittings. Quoting $675 for 20 feet of pipe and 10 fittings can only mean a few things: 1) this guy is a crook, 2) he wants to see if i’m an idiot, 3) he did the quote wrong, 4) he really does not want the job.
I need to keep looking….so far 3 phone calls/emails and no responses.
Insulation, Vapor barrier, and Rebar
In my last post I had the center part of my slab filled in with gravel. This weekend I compacted that gravel and brought the level to within 2 inches of the top. I then installed 2×8 foot sheets of insulation over the top.
The vapor barrier is a product called Tu Tuff. It’s a 4 mil plastic sheeting that reminds me of potato chip bag material. The vapor barrier is laid over the foam and tucked into all the nooks of the slab to hopefully keep moisture out of the slab.
On top of the vapor barrier I installed rebar (which is pretty expensive BTW). Code requires me to have two 1/2 inch pieces at the bottom of the footings and one at the outside edge near the top of the slab. I also added some cross pieces to make the slab even stronger. Before the pour I will install some mesh over the top of the rebar just because.
You will notice that 1/4 of the slab is undone….thats where all the plumbing needs to go.
The front porch will be about six feet deep and will sit on concrete piers in front and be bolted to the slab. Its much easier to install “J bolts” than drill fasteners so I laid out the bolt pattern on the foam insulation and stuck the bolts in place.
My concrete piers I just dug three holes 4 feet deep and used 6 bags of concrete and some rocks to pour footings. The building code requires 13 x 13 inch footings 6 inches thick. Mine are probably thicker and wider as I just filled in the bottom of the hole. Note that I also installed some 1/2 inch rebar to prevent the frost from shearing off the piers (happens a lot here).
The last thing I did in preparation for the plumber was to install mock walls so the plumber could figure out the exact locations for everything. The shower pipe will have a 12×12 box around it to allow the plumber to install the trap post concrete pour (rebar stake in box). The large box is the form that will create the recess for the well expansion tank
