drain pipes

master bath drain pipes

master bath drain pipes

this photo shows the drain pipes for the master bathroom, which are made from CPVC. living building challenge has red listed this material. unfortunately, the house will not meet the materials challenge of the living building challenge for this and other reasons that i will discuss when the slab insulation goes in.

the alternative is ABS drain pipes. the plumber was not comfortable using ABS and feared that there might be leaks. so, i am using PVC drains. overall i am minimizing its use.

not prime farmland

web soil survey detailsleed discourages development of prime farmland, parkland, or land that lies within a floodplain or that is identified as a habitat for endangered species, or that is within 50 feet of wetlands or within 100 feet of a lake or stream. well, that’s my over simplified summary of what they say.

i’m in the process of documenting that the lot i’m building on meets these criteria. the first one i checked is prime farmland. it turns out that there is a department of agriculture website,¬†, that informs whether land is prime farmland. i got this pretty map from them. the orange target is where the lot is located. it’s in a soil type GhB, which is designated as glenelg urban land complex. according to the website, this is not prime farmland. interestingly, the nearby GgB, in green, is glenelg loam and it is prime farmland.

the palindrome glenelg is the name of a community in howard county.


back to the house build

OLYMPUS DIGITAL CAMERAthree courses of cmu have been placed on top of the footings. this will facilitate accurate slab penetrations for plumbing and electrical chases. the builder, taz ezzat, recommended this. with this suggestion and many other considerations, he has not missed a beat.

i recently learned that cmu stands for concrete masonry units. i used to call them cinderblocks; why the name cinderblock did not persist in the building trade remains a mystery to me.
