OK. Looked over an apartment building in a poor neighborhood. The owners were working to renovate it, but got shut down because they had no permits and the workers were cheap clowns. So, the owner is selling it and someone else will take up the renovation, hopefully they will have enough money to do so.
In any case, each unit (4 in total) had new water heaters, but their installation left much to be desired.
Can you spot all the defects? (this is Chicago, so your local requirements may vary.)
Flex gas piping is not allowed (unless a movable appliance) and the drain pan is not, itself, drained. Flexible supply piping is also not allowed around here.
This place was a real do-it-your-selfer’s cluster F*@^. They were duplexing, up, the 2nd floor units to the large attic area, but just kept the 2 x 6 ceiling joists. BTW: The 2 x 6 joists were also top notched for new water and electrical. What a mess.
Hard to tell for sure on some but here are some that look like may be defects. And may vary by area.
No sediment trap
Flex hose on gas
No shut off on gas
No TPR discharge
We can not put TPR on top
Not sure what vent is but does not look good
Are vent pipes screwed together underneath tape
