Rosealee, yes, you would have to reduce pressure to optimum which is 15 psi. You would have to step your pressure down and match pressure and flow rate to the heads in the flower beds. It is not that difficult. Several in-line pressure reducers would do the trick. These deflection-plate type of heads are also affected by very windy conditions. Why not go drip tape? That is the best system to counter windy conditions. The drip type also would require reducing the water system pressure for the flower beds only 15 to 25 psi. What is your current water pressure and flow rate per zone? Aloha

You can also use Bonide Fung-Onil. Both the Ortho and the Bonide have the same concentration of Daconil. Some stores carry the Bonide but not the Ortho. ****** YES!!! bcday knows that I'm growing quite a few tomato varieties that are new to all or most b'c I send her the seeds for same and she does most of the seed production for SSE listings, etc. So like a jerk I called my local Agway Saturday not remembering it was a Holiday and also called the local hardware store; they weren't home either. This AM I called Agway and at first mentioned Ortho Garden Disease Control, they had none, Steve called the main warehouse in PA and they were totally out and said they did expect some in in about two weeks. So then I mentioned the Bonide Fung-Onil and Steve actually had a pint of it in the store and NOW! I kept saying thru this whole conversation that I wanted the 29.6% chlorothalonil and he kept asking me to spell it and then said he had copper spray which says on the side Blight and I said no way. he said you really do know what you want, don't you. LOL He was not in the mood to be told that Daconil acutally blocks the LB and fungal foliage receptor sites on the leaves.( smile) Then call Freda, Freda will pick it up tomorrow and then we see if my pump sprayer is still alive, but if not, she can use the 2 gal watering can just as well. Everything will get it, the tomatoes, potatoes, cukes and squash, the latter two primarily for mildew and Daconil is great for mildew. I'm just not willing to take a chance on the special tomato varieties I'm growing but I can't get out there with the walker to even see if anything is going on with the tomatoes. Freda will do that tomorrow, but then there's more rain, heavy T storms predicted today and tomorrow, so we may wait until Wednesday to spray. Carolyn

I just went thru a similar experience this weekend. We had purchased a 6 inch sunflower type and came to realize we don't have the water pressure to support it. Determine in minutes how long it takes to fill a gallon jug. I determined my water output was 2 gallons per minute. the sunflower unit I had was 2.5 gallons per minute. Sounded close enough. I snapped it in and the water ran hose like out of the sunflower, just didn't have enough pressure to dispurse water thru all the holes at a steady enough stream. So maybe doublecheck your pressure to see if you can support either fixture. Just a tip I learned htis weekend!

This has discussion has a lot of great information. I'm not sure if everyone's questions have been answered but we have a very in depth article on our site regarding the difference between the Delta 17 and 17T series trim kits. It gets pretty heavy into the details. Others above have given a pretty good explanations in this discussion but I think some aspects may still be a little unclear. Here's a summary of the differences detailed in our article. 1) Water pressure: 17 Series cartridges operate using pressure balancing techniques as opposed to actually sensing temperature. This means that water pressure from a 17 Series trim will be less than a 17T Series. 2) Temperature limit stop: If you live in an area where seasonal temperature differences are greater, you may have to adjust the temperature limit stop in your 17 series shower periodically. You will never need to do this with a 17T series. 3) Accuracy: 17T keeps the temperature in a tighter range. If you adjust the temperature handle more often the 17T will give you more predictable results with less fiddling around required to get exactly the temperature you want. 4) Shower systems with multiple spray outlets: In the case of a shower system you will require more water pressure and a 17T will be better. You will also get better pressure from a standard showerhead with a 17T. These are some of the reasons the price is higher.
