The tank is only required when the water supply system incorporates a backflow prevention device, check valve or similar device.

If you want it in the cloud, use Google Drive or I Cloud to store it so you can access it from any device.

Valves are just like any other mechanical device and it can wear out over time.

Our low cost of living compared to other major cities (Chicago, New York, DC, LA etc) is attractive to folks from those markets because you can get a somewhat downtown experience, pro sports teams, culture/sights/attractions at a comparatively affordable price.

I currently have one tenant living with me in my 4 bed/3 bath house in Boulder who wants to continue living here so the plan to to find 2-3 more people to fill the other rooms over the next couple months while I find a new place to buy or maybe buy a travel trailer and live/work out of it.I have a full time job as a sports marketing manager in the outdoor industry but work out of my house and like to play in the mountains as much as I can.I feel like I have learned a lot about home renovation/construction while owning my house for 6+ years and look forward to learning a lot more from this community.

This device would seem to require WiFi, which I would not have at a rental property.

No holding back.But right now I feel like I'm that kid from High School that loves to play sports, but can never make the team because he isn't big enough, strong enough.. or even good enough.  

This is along the same lines as professional sports figures that go into the private equity business...

A closing device shall be installed on all screen doors.So if you have central AC and your renting a property out and local codes read as above a landlord does not need legally to provide screens.
