Electrical advice

Need some advice from some of the electrical wizards on the board. When built my shop I ran a piece of 1 1/2" pvc conduit out into the yard where we planned to install a water feature. We have now completed it and I want to run the electrical to power the pump and lights. Right now I have a short piece of pvc sticking up in the yard (with wire pulled and capped). I need a box to mount on the pvc (glue joint) and run another piece over to the water feature. I need something like this ( http://ift.tt/1wh9rwB ) but in 1 1/2" and without the mounting ears. Can you tell me what that box would be called and where I might pick one up in Houston (prefer NW if possible). Once I run the conduit to the water feature I need a box to plug in the pump and lights. Lights have a timer built in to the power supply but I will need a timer for the pump and can ether cut the plug and hard wire or install a timer to an outlet and plug the pump into it if that is possible. Any advice on these 2 boxes and timer would be appreciated. Thanks in advance.
