I have a 36"Wolf induction cooktop and the Wolf downdraft behind it, on a 11ft long center island. If you are already used to cooking on an induction cooktop,you know that any drops of water or any slight touch, will change the element heat up/down. It's important to have the delicate controls off to the side somewhere, so one doesn't inadvertently change the settings and burn the food. The burners, 4 of them, work great. I love how fast they cook. The 5th burner, the largest one, worked for about 1 year, then quit. One cannot just replace the faulty burner. One has to replace the whole cooktop, so I didn't do that. It's a transistor thing, the repairman said. The downdraft went up/down, with a concealed switch. It looks great, but only comes up about 12-14" tall. One day, it wouldn't retract, so it's stuck in the upright position behind the cooktop, and it doesn't turn on./off. Again, I have to replace the whole thing, according to the repairman. I have had this cooktop and downdraft 10 years. Look at all the choices on the mkt. today. I had no choice, really, as induction was new to the American mkt. I also recently bought a SubZero ice dispensing side by side, refrig/freezer. It's OK, but holds less than the KA I replaced it with. The best DW I have found, is the Bosch, with 3 racks. I can fold all the racks down to fit almost anything. A lot of DW do not have fold down tines. You do have to use salt to keep glassware sparkling. TRM

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.

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
