I've build decks for the pools. I've used old 2x6 boards I had laying around. Each pool has one deck and 2 stair cases. It is best to put the stairs next to the pool, because the ducks tend to run along side of the pool to find the stairs. This also allows me to change the configurations anytime. I can put two decks together and put a pool on each side. Or run it singular like the large pool with slide. Each step of the stairs is 3.5" high and they move up and down with ease. I've also shown a picture of the drain assembly. I was going to use a shower drain, but the prices for the whole assembly would have been to expensive. I went for a threaded ball valve with a threaded nibble from inside using two large rubber gaskets on each side of the pool. I can get another piece so I can hook up a garden hose. Drain assembly per pool was under 5 dollars each. Now it takes only a few minutes to drain and it will leave about 3/4 inch water on the button, that is easy to lift and I can hose out the rest. In winter I can just move the pools into storage. The big pool is out in an area with little shade. I've basically got some large 8 foot T-posts and bungeed a shade cloth over it. PM me with your private email address, if you like jpg files with instructions on how to build these decks and stairs. Ultra easy to make.
So here are the pictures:
For those that want to put in a ball valve drain. Here are the parts:
3/4" x 1" PVC Male Adapter @ $0.77
3/4" Threated PVC Ball Valve @ $3.17
Two #11 O-Rings (3/4") @ 1.97 for 10 pieces
All pieces are available at Home Depot or other hardware stores. Make sure to cut your hole as tight as possible. Put the Male Adapter with an o-ring inside of the pool, add another o-ring outside and screw on the ball valve. No glue needed. Really simple.
You can also buy a hose adapter, which you can screw into the outer part of the ball valve. This enables you to connect a garden hose to it, so you can have the dirty water discharge anywhere in the garden.
3/4 In. x 3/4 In. MPT x MHT (Male Hose Thread) PVC Hose Thread Adapter @ $0.99
The prices given are from Home Depot. They do not include sales taxes. Take this list with you to the hardware store and have someone help you. Make sure they all screw together before you leave.
Remember to fill up your pool once and then mark the location to cut for the drain. The pools have the tendency to pull down a little bit. Do not put it in first and then fill the pool only to find out that you are too low and the valve gets pushed up.
