These are cheap, plastic things that some plumbers say may fail.Ammonia was often used in plaster work back in the day both for the plaster for walls and for moldings. 

As to my costs, the 140' of  4" plastic pipe I bought, was less than $300. 

Not the same as pex, though both are plastic. 

UPDATE:I went by Lowe's on my way home today and did not like the look of the plastic stick on tiles at all.

It's impossible when they get that big to keep up and get to the houses on turnover day, (Fri, Sat, Sun) with the traffic when everyone else is trying to get to the same place on the only road in or out.I think it's well worth the investment as I already own 3 (long-term rental) homes down here.

What I would do is check your basement floor first by putting a 3 foot by 3 foot piece of clear plastic down on the floor first and tape around all corners.  

Well long story short he saved on the electrician but ended up causing a short that fried all his appliances and nearly set fire to the place.

One of the reviews said the Delta "chrome" cover plate was plastic, just like many of their faucets these days.

I also speculate about melting the recycled milk jugs and making white, soft plastic tiles for bathroom floors.

To be blunt most in the small fry real estate world simply aren't sophisticated enough to account for risk in their dealings.
