Like I said before, pex and poly are the same outside diameter.

Also there is a 3" diameter chunk missing from the top of the tub where something fell down on it.

States seem to have a trust fund set up to help home owners with some of the expenses in the event of a leak.BTW, our tank was 42 inches in diameter so the costs I indicated relate to that.

These walnuts are 3~4 inch in diameter and quite heavy, so they can make a dent in the cars I think: https://www.farmanddairy.com/wp-content/uploads/2014/09/DickieBirdFarm-BlackWalnuts.jpg The tenant wrote to me saying if I can trim the tree or find some other quick fix because they noticed dents on the hood of the car.How do you suggest I should handle this request?

Considering the diameter of the wheels and the RPM of the engine and concluding the car will go faster is a bad conclusion.In RE, the NPV is used to value a long term lease or better, an option.

If installed correctly you should see a 4" diameter PVC tee submerged into the effluent(milky substance).

You'll need three or four sheets, so that when stacked they are slightly thicker than the height of the drain pan.Next, draw a circle on each sheet, slightly larger than the diameter of the drain pan, and cut out the circle.

The big things you want to make sure of is  1) the piers are spaced appropriately to support the home, 2) Piers are an appropriated diameter, there is a big difference between a 12" diameter pier and a 10" diameter pier (which many companies use), 3) Make sure they piers go deep enough into the ground; at least 36" below surface and they must "bell" out to ensure stability.  

After Ron left I explained to the guy what the real difference is, which is the drain version has a sweep that makes it possible to snake, and the inside diameter of the drain fitting guarantees a smooth integral bore for gravity draining when connected.A day or so later I was at the same Home Depot looking for a 20A double pole switch in the electrical section. 

Speaking of gardens, the 3/4 acre garden surrounding the house is overgrown, but there are some amazing old plants hidden amongst the chaos - I found a rhododendron with a 30' spread, whose trunk was 8" in diameter - quite a specimen this far north.The main house has seen the anteroom and library/smoking room (on the right-hand side of the main entrance) turned into two bedrooms - with a washroom and laundry closet added between them.
