question on trenching e.t.c.

Any tips on trenching for the pipes? I'm renting a ditch witch probably some time next week. One thing I would like to know is how deep of a trench do I dig in order for proper head placement. I am planning on 6" risers, blazing saddle taps and 4" rotor heads for underground placement. I'm thinking about 1 foot (12") or would that be a bit much? Also, i've got some fill on the lot compacted about say 4". Underneath that in some areas may be some lime rock. Would I have problems using the ditch witch in these areas? Thanks, and send me any tips using this trencher as well

Why not rent a pipe puller? No trenching envolved except for where you install the heads

I haven't seen any vibratory plows (pipe pullers) for rent where I live. Only follow behind trenchers like the ditch witch. Any tips?

I rented a dith wich to run water to my barn and it was very easy to use and the trench was 4 ft deep and about 150 ft. One thing that I can think of is to try not to run over trenches once dug the the ditch witch. 1 ft would be good but if you live in the caymens youu may be able to go a little more shallow because you dont have to worry about freezing. The only other tip is to find a pipe puller if you can it will make a lot less mess and a lot less work.
Thanks,

Pete

The only reason I was thinking around 1' deep was because I didn't want the sprinkler above the ground when mounted to the risers. So, what is a safe, shallow distance that I can dig to ensure my sprinkler heads are level with the ground? How many hours do you think I could do this in (ditch witch rents by 1/2 day or whole days)? thanks

10-12" is plenty. You mentioned riser. Go with flex tubing and blazing saddles

The guy here advised me against flex tubing for some reason, but I do have the blazing saddles. Also, I have risers that have already been ordered [:(]

Is there a big advantage of using flex tubing over normal risers?

Yes funny pipe is very easy to work with and gives you lots of flexibility with adjusting height.
Thanks,

What connectors/fittings do you use with funny pipe anyway? Don't know too much about it. i think the Lowe's guy steered me from it due to reliablity, but I don't know how long it generally lasts.

I use again blazing saddles with funny pipe threads from sprinkler warehouse and then mpt 3/4" funny pipe stree elbow(90 degree)connector again found at sprinklerwarehouse or even home depot. The elbow connects to the rotor or use 1/2" for spray and the blazing saddle connects to the poly pipe. Now both fittings have barbs for funny pipe so you connect the 2 with funny pipe and you dont use any clamps. It is very simple and works excellent.
Thanks,

Pete
