Hello. We are planning on laying some concrete and doing some other backyard work. In a couple of years we would like to add a pool. Having said that, what do we need to do now, before any work is done to save us having to tear up concrete later. Is there a list of what items we need to do now that cannot be done later? Thanks

Need a replacement light for my spa. Actually, the one that was installed when I inherited it was rigged up from an outdoor flood light, held in place with electrical wire around the plumbing...! My spa is about 15 years old, and has a plexiglass window by which the light shines thru. There is a lock ring on the tub side that attaches via screws to the ring on the other side. Not sure where to look to find the correct light for this, or if I need to replace the plexiglass window with an actual light lens. There is no way to safely support the light from the inside, so it would have to attach directly to the tub from the access panel. The spa is 120V, with no low voltage transformer for the light. Thanks !
