I have since searched this website for irrigation recommendations and have found three I will try to see what they think and hire one to fix the problem. Will let ya know how it goes. I just love TOTV and all the helpful info here on this site. I will have to make it a point to post some positive experiences I have had with contractors I have used since we moved here in February. Got to return some of the info I have received so others can benefit too. Thanks for all your input. Much appreciated.

I had Don the Donunut man do all of my sprinklers about two years ago. Give him a call.

It may be that the downward pressure exerted by the flow of water out of the sprinkler head may be enough to gradually push the sprinkler head lower in the damp soil. Being that the soil is sandy makes me believe it could happen over time. Think of when you are holding a garden hose. If you let it loose, the back pressure causes the hose to move on its own.

I don't have a clue, but did call Chip from Action Irrigation this morning and have an appt. tomorrow to access the situation. Will keep you all posted. Thanks for all the input. I didn't have the donut guys number and thinking it may be a little more work involved, just don't know at this point.

Just thought I would give you all who were so helpful an update on what transpired with my irrigation sprinkler sinking issues. Had Chip from Action Irrigation come over and access and they really were not down too far, just needed some digging around all of the donuts and changed out 13 heads of 39 for more better coverage. He and his associate were awesome! Lawn looks great and my irrigation is now purring like a kitten again! Thank you all for all your input. I love TOTV! Any future issues, I will not hesitate to call Action Irrigation again. Prompt, courteous and gets the job done above and beyond. Very reasonable priced too.

DebbieB,

Glad that things worked out so well. Thanks for the update. That's great forum etiquette.

Your irrigation system needs a tune up every so often.....be it yearly or every other year. The longer you wait the higher the bill is likely to be for the heads go bad and its the heads that cost money.

Glad your problem is fixed...!

In my humble opinion, the sprinklers do not sink. The sod establishes roots and is higher than when initially installed. You can see this by the driveway and curb. This happened up north without donuts and without heavy mowers on the lawn. Cut-off risers are available at both big box stores for less than 40 cents each. Dig around the head to the depth of the elbow where the sprinkler head is attached. Unscrew the head and insert the riser, cut to the desired length, and re-install the sprinkler body. Recommend removing the sprinkler nozzle to flush out any sand, and to clean the screen. Install the nozzle and adjust as necessary. I raised 60 heads this spring, and they are still at the appropriate level.

I agree, risers are inexpensive.

Get a new landscaper. The soil around it is heaver than the donnut, and the donut would have to push the pipes dawn as well as the sprinker head. Putting on an extention will fix the problem and they are very easy to do. Just dig around them and remove the head and add the appropriate extention. They are hand tightened.

Easy
 

There most likely not sinking. As the grass gets established it gets thicker it raises higher, The problem is easy to fix. Go to home depot and buy extentions at differant lenghs. You can also buy ones that can be cut to any lenth you want at inch increments. The work is not too diercult. You dig down as far as the pipe the hole the same size as the donut. Remove the assembly thats attached to a tee or elbow and you can add the extention. The parts are all hand tight.

We've lived here several years and always had an acquaintance do our irrigation, but I had a major problem with my grass browning out and saw Chip being highly recommended on this board, so we called him. He did an excellent job, I had several sprinkler heads leaking and wasting water, and he just "knows what to do" - he's great, plus he is married to a Village realtor so they live here, are here for the duration and he backs his work 100%. Great guy.
