I've used Lowes Valspar 4000 eggshell Gravity in 12 or so SFHs.  

You can see this is already having an impact in the Gravity and Gravity 2 project.

Hey JimThanks for the input.I met with an engineer to confirm the topography is suitable for gravity feed to the sewer line and that the site can support some type of subdivision, i.e. streets, infrastructure, etc. 

I have installed several on-demand systems in the majority of our rentals for both convenience & gravity exhaust safety.

Preserve and protect your rental while waiting for authorities.Get a dehumidifier running with gravity drain to a sink, ASAP. 

Broken pipes will leak, but if the water is shut off, they will only leak the amount of water that they are holding and that gravity forces out, which is quite a small amount. 

They ran a basic test filling water at the cleanout and letting it sit via gravity. 

My huge head has its own gravity field!

If they don't like the tree, they should not have bought the house.Leaves fall, that's how trees work, and gravity has been around since they were young (it's nothing new).If it were mine I'd tell them they can get a leaf rake for under $20 on Amazon if they want their own property raked.

I've also spent time reading blogs, listening to podcasts and reading books but you never really know the gravity of what you are getting into until you actually DO IT.
