My house is 10 years old, and the dirt has really settled around it. I dumped about a dozen buckets of dirt in last weekend and raked it out.

I got electrician in this morning to put in frost sleeves. I would highly recommend that any conduit attaching to the house and going underground have these, otherwise they WILL pull away from house at some time.

The putty is covering a hole where I am going to reroute the sump pump outlet into. The tile goes down to my gully.

I did power line work for years, when installing the wire you need to put a loop (leave slack) in side the box. You can't just come strait into the lugs. But yes the frost sleeves are nice.

Poured concrete walls? Looks like the wall ties never got snapped off.

The worst ones have elbows in the ground that helps to pull or push on the conduit.

Dave, was the brick pattern in the form? How's the Massey EFI doing and are you going to get any horse power readings? Greg

David G · Sep 24, 2014

Yes, the brick pattern is in the form, and I noticed that the ties were not knocked off, will put that on my list.

I have not gotten anything done on the MH44 EFI the last month. I am trying to get other things done before winter.

I have the parts to finish up the loader conversion on my 6610 to a separate CCLS valve this weekend.

A couple of years ago during the height of our drought there were four new houses here that caught fire. The house settled when they didn't water the foundation and the box ripped off the house starting a fire.

I bring conduit out of the ground in Rigid galvanized. Yes, it has a 90* elbow, but mounted with unistrut and strut straps, I have yet to have one go any where. it also helps to backfill around the conduit with sand/gravel near where the conduit emerges.

I personally hate bringing PVC out of grade. In my opinion, you are begging for trouble.....but then again, my way of doing it is a bit more expensive also!

We never put an elbow under ground. We ran the wire straight down from the pipe at least 6 inches before going lateral. If using metal conduit especially. The frost heaving can cut the wire at the end of the conduit.

I have seen wire shorted by an elbow more than once.

Plastic pipe not so bad.

With the elbow what keeps the frost from slicing the wire at the end on the pipe.

I have seen a short at the end of the metal pipe more than once with a lateral end on the pipe.

Always ran the wire straight down out of the pipe 6 six inches before turning to avoid a pinch point.

Way back when I practiced we ALWAYS used Rigid or IMC up out of the ground (with sweeping 90 degree and plastic bushings etc) to an LB or J Box etc as I recall it was an NEC requirement for strength it was so exposed. I thought plastic was a no no for such use as the out of ground riser??

I think 90% of residential uses PVC.

Supposed to install a bushing on the threads to protect the conductors.
