Our adult tenants with no children have asked to put up a 13" diameter, above ground pool because it "helps her back pain."

And of course the overall diameter of the pie grows and shrinks over time too with the total volume.

How thick was it (diameter)?

(I put my gym membership on hold that winter).Then, I installed industrial-grade perforated pipe that was roughly 3’ diameter (the type of thing you might see kids crawling through at a playground), and three industrial-grade sump basins, each of which were 65+ gallons (large enough for a full-grown adult to crawl into).

Typically the build up has constricted to less than 50% of the original diameter. 

Also buried the sump line at to high of a depth and to small of of a diameter pipe that he fried our brand new sump pump. 

Time your purchase.  1,600 square foot ranch,  Entire rooftop balcony, mahogany furniture and doors, marble top kitchen and bathroom, tile floors, double pane glass, porch, plastered inside outside.  5 foot diameter trees around .  

I've heard of doctors in up-scale rentals burn holes in laminate floors 2 foot in diameter. 

I have been charging $10 per inch on cracks in fridge plastic, cuts in flooring, new chips on tubs/sinks/appliances, for the diameter of carpet stains, and per nail hole in finished woodwork.

Under the Telecommunications Act of 1996, you cannot restrict a tenant from installing a satellite dish on the unit, as long as its under 1 meter in diameter and it is installed in an area where the tenant has exclusive use (patio or balcony, or a roof if a SFH).
