SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

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

<br />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?

<br />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.

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

<br />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?

<br />Yes funny pipe is very easy to work with and gives you lots of flexibility with adjusting height.

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.
