I don't know what you are referring to when you say "drain back". This valve has three portals and it allows you to direct fluid flow from one of the portals to one of the two other portals. For example, I use it to direct backwash from my pool to either the backwash pit via a pvc pipe or into a hose that I can direct wherever I need to direct it. I just turn the handle to direct flow one direction or the other. You can change which portal is the input by taking the valve apart and restructuring the internal control components. That is fairly easy to do - just requires a phillips screwdriver. It works well. I don't know what you are referring to when you say "drain back".

Sorry I don't know what a drain back valve is. It's a 2-way selector. It has an inlet from the pool. From there you have a choice for filtration or water evacuation.

No, it does not. We place ours on the side to drain; however it would be easy to drill drain holes.

No but there are indications of where to drill the drain holes. This is easily done!

no unfortunately it can not. It does not provide a drain valve. You have to disconnect the unit from plumbing / electric and tip it over several times.

Unfortunately no. There is no drain plug. Just a fill port. I used sand to fill it and have forgotten about it ever since. Compliments my patio nicely. Hope this was useful.

I bought mine several years ago and don't even have it any longer, but no, I don't remember any drain plug.

No, it was just a hole. But the faucet you get should include a matching drain plug (same finish). Most of the newer faucets come with the full assembly

To my knowledge this fixture does not have a backflow device. You do not need one on each fixture, your plumbing system should have one backflow preventer for the whole system.

Winnie, sorry so late on the reply. This valve came exactly as pictured. It was a very good price and worked perfect for our solar panel.

It comes with a drain. I had bought one separately because that detail was left out.

It does not include the backwash valve. I mated it with thePentair 261152 two inch Threaded Multiport Valve.

No you have to purchase one separately. I don't have the item # to hand but it was listed on the page. I got a pop up drain. Appears to work well

Xinyu, The TK-SC6 controller comes complete with three sensors: Two for the top and bottom of your main water tank and one for your solar collector. The solar collector sensor will probably need you to supply extension wire of proper gauge in order to reach roof-top collector. This extension wire is easy to find at most hardware stores and is inexpensive to buy. If you are using controller for a "drain back" solar water heater type, you will need no valves at all. The controller is purely electronic and uses algorithm logic to turn you recirculating pump on and off at the proper time and duration. In other words it is not connected in any way with water pipes but wired to the pump only. Hope this helps, jack

No it does not. You will need to purchase that in accordance with your local plumbing regulations.

Yes. It comes with a drain hose and an overflow drain hose. Can set it up to drain with one hose or use other if reservoir becomes full. Set mine to continually drain.
