is that psi at the head or the main line? if at the head over pressure may be the trouble. the 1800's were designed to work at 30 psi so misting may be why they are falling short. some possible options are changing to streamer nozzles or switching to pressure regulated heads.

Ok so I am narrowing down my choices. I know that I want a very modern look in a house with not too much light. This is the rift and quartered white oak flooring with Champagne stain I bought. I wanna paint both walls and trims (the latter glossier) with one of these: 1) Chantilly lace by BM (warm white but no undertone: LRV=92) 2 )Simply White by BM (more yellow undertone than Chantilly Lace: LRV= 91) 3) Extra White by SW (LRV=86, slightly cool undertone) 4) High Reflective white by SW (LRV= 93, people say warmer than Chantilly Lace) Which one do you suggest? Questions are: 1) Is there an undertone of white that makes a house feel more modern? 2) I have some blue furniture, and the felt of the pool table is blue. Should I go for a less warm color like Extra white? 3) Isn't a less warm color such as Extra white gonna make the wood pop up? 4) Should i go for Chantilly Lace (LRV=92) to maximize brightness in the house? Here is a picture with the Simply white and Extra white next to the Champagne plank. Still waiting for the brighter samples (Chantelly and High Reflective).

13 Meters x 12 Meters ==>> that is a huge garden ... and you want ALL the sprinklers to water it all at one time.. a few pix of your garden will help us help you ...... your flow rate is the least of your problems ... physics might be the bigger problem ... btw.. as to the supply line ...the smaller the pipe.. the slower the water moves thru it ... plz explain what you are growing.. and how you are growing it in this monster garden bed.. if you have lined out veg crop.. then drip is definitely the way to go .. and you should look into zones ... no need for electric switches.. water one or two zones a day ... cycling over a few days all the zones ... ken

i am going to use them on an upcoming remodel. I think sometimes installers poo poo things that are difficult to install
