I know i have posted before about this. The pool itself is a simple unit that most of those who are a bit handy could make. the shower is a bit more tricky.
I have rebuilt the unit and have been working on how to have a shower as well.
The main pump that runs the pool is mains power and the wire may need to be protected if you have a chewing bird. It runs on a timer and just runs a few times a day to flush the pool.
I have only just got the shower switch figured out. So they have not used it yet. The 12volt pump is very noisy and I am building a box to put it in to quieten it down so it does not freak them out. Also I may have to back off the pressure of the shower heads, as they are fairly strong at the moment.
I now have to figure how to get them on to the perch switch.
The shower is run with a 12volt pump and is switched on by the perch. The photos are of the prototype, so please do not berate me for the mess. I will have it all boxed up and then it will be harder to show the construction.
There are more photos on clawinnz Photobucket account. They show the first build and the new one. There are also 2x vids on You Tube account clawinnz.
I am happy to answer any questions if anybody wants to build one.
