Questions in relation to a rectangular shaped lawn - domestic
Does anyone have a opinion on using Hunter MP Rotators vs Rainbird RVANS?
Also articulated risers vs non articulated.
The pros explained to me include the benefit of being able to finely adjust the articulated risers to the right height without glue or tape or adding in risers. A opponent of articulated risers said you have to dig out too much dirt to enable them to move in the first place, however if its easily dug soil and lawn you can cut out in easy rectangle shapes I dont think thats too hard to reinstate.
Whilst one can add a small riser to a system where the popup needs to come up say 20mm, its much harder if it needs to down, i would have to also dig out alot of dirt and cut, glue in elbows further back along the line to lower them?
Another benefit is that cars and heavy vehicles do less damage as they can move in the ground a little. A opponent to this said he just uses the heavy concrete surrounds. Though thats more ugly.
Popup Height - is 6inch popups superior to 4 inch? what are the reasons. Presumably one needs more pressure to raise 6inch popups.

The MP rotators would be my preference over rainbird.
4 inch pop ups should suffice with a buffalo. If you go bigger you are just adding to the cost and effort for no real extra reward.

I don't really have an opinion on articulated risers as I don't use them. To me they are a convenience for maintenance contractors as they don't have to carry a wide range of riser lengths. In my experience they break just as often as the rigid ones.

Hi Lakeside Paving, thanks for the response. Again interesting to receive feedback, one guy I met was adament they can take heavier vehicular loads without breaking as often as standard ones but your experience hasnt shown that. Which leaves me neutral !! on them.
I will be the maintennance guy, probably.. at my own place so the convenience would help me, that said as its my own place, i dont generally worry about the time component in fixing things either.

If you know the depth of your retic lines and the height of your pop ups you will know what height riser you need. Just keep a few handy and you can't go wrong.

Lakeside, I meant to add on the Hunter MP Rotators vs Rainbird RVANS
I was told that RVANS are better suited to bores, as they throw a larger amount of water out and therefore you can have half the runtimes, also means less bore pump wear and less overspray onto walls if the conditions happened to be windy. The RVANS with the yellow top can also be pulled up to self flush whilst the MPs do not have that ability at all. Obviously both these units are mostly unservicable if they clog up compared to standard Toro heads which you can use compressed air or fine wire on.
Also what about Gear Drives? or is that really going too far. The lengths are about 14m by 6m and 14m x 10m.
