I have also completed most of my trenching.
My trenching for gas and electrical was about 110 feet. I used 1 1/4” electrical conduit and 1 1/4” poly gas pipe.
I do not plan on running a propane heater (my plan is to install a heat pump/chiller). But having the larger gas pipe will allow for easy installation if I change my mind about a propane heater (my neighborhood has a central propane delivery system). I will have a fire pit that will have gas; so installing the gas pipe was not a total waste of time and money.
My electrical wire calculated out to 3 awg (100 amps). Even with a helper, wire lube, and a pull rope, pulling the three 3 awg wires and one 6 awg ground was difficult. The total pull length was 125 feet, and I had to install a pull box due to having more than 360 degrees of turns in the conduit. Copper wire is expensive.
In the electrical/gas trench, I included a future irrigation wire and 2 cat6 wires (one for the swimming pool automation equipment and one for a future Poe camera).
Code in my area does not allow you to hook a swimming pool auto fill to an irrigation system. So, to install the water auto fill, I had to trench about 130 feet on the other side of my house and tap into the main water supply. I also installed a water shutoff valve near the main water supply for the auto fill. While not installed yet, I already have the RPZ for the auto fill. I ran approximately 200 feet of pipe for the auto fill and have another 20, or so, feet to go. About 70 feet of the water pipe passed through sleeves (i.e.,2” pipe that I laid before shooting the remaining retaining walls).
