    my pump pit deck cover

    I just finished my pond project and the last thing was the deck cover for the pump pit. The pit is 6 x 9, but I wanted the cover to also cover the drain cleanouts and autofill valve. So, the deck is 6 x 10. I contemplated for months before coming to this design. I had a custom frame made from 2.5" aluminum tubing. The tubing is 0.188 thick, fully welded at all seams. This made for a very stiff and light frame. I attached Trex decking to this frame to make the deck. To lift the deck, I installed a linear actuator capable of lifting 1000 lbs. The bottom of the actuator is supported by a clevis pivot mounted onto unistrut, all embedded in a concrete pier. I ran the control to a DPDT switch mounted high on an adjacent pergola post. Despite it's size, there is only about 1" of sag on the opposite corner from the actuator. The hinge is an 8' heavy duty aluminum piano hinge with a 5/16" pivot pin. It is through-bolted to the aluminum frame and lage screwed to double sill plates on the pit. While working in the pit, I install a fixed aluminum support at the sag end for safety (not shown in photos).

    Thanks. In general, I love stone, big stone. But, after months of humping huge boulders around, I'm done with it. If you want to see more rock work, see link to the photo gallery.

    Thanks. Things are pretty tight in there. Using unistrut really made a difference.

    That is really swell, I like the idea of the aluminum framing -- no rust! How heavy is the Trex compared to redwood, if you know?

    I don't know about redwood, but the trex is definitely heavier than pressure treated. I found the density of Trex on line and calculated that on this 6x10 deck, it weighs about 300 lbs. With the Aluminum frame, I'm estimating about 450 lbs. total weight.

    I love how your waterfall is actually a room and the door side looks like an ancient ruins - extremely creative way of having a waterfall fed by barrel filters on a level lot!

    Thanks GoldieGirl. Yeah, I had no other way to hide the barrels, and make a hill at the same time. It did add quite a bit of work to the project, though.

    Redwood is extremely light. Trey on the other hand is very heavy. Love them both.

    I guess I prefer Trex these days because of its durability and no maintenance. Used it as trim on my filter shed. It looks great and is very easy to work with.
