Washing machine draining pan installation question

Good evening! We recently had our kitchen redone and we added a refrigerator that has a water connection. Our contractor tappled into a cold water line with a saddle valve and there is a 1/4" line feeding to the fridge. It's a Samsung refrigerator with the Samsung filter and the speed of the water dispenser is piss poor. I'm wondering if it has to do with the fact that it's connected with a saddle valve? I imagine the water pressure that IS going to the line is fine because the other end of the line is feeding to outdoor water and that gets plenty of pressure. I'm asking this because I'm wondering if I install a T-fitting, in order to eliminate the saddle valve, would that raise the pressure? Or would I be wasting my time? Thanks in advance!

I'm getting ready to do my kitchen and have some very basic questions about venting! First I'm in Northern NJ, and the house is old -- from about 1880. The kitchen has not been done since maybe the 1950's. I currently have one sink on the outside wall, but they did not do a very good job at venting and I believe it is not currently up to code. Right now the sink is vented straight out horizontally from the drain pipe thru the outside wall, and opens below the window above the sink! So I think for starters thats a no-go. I'll be gutting the kitchen so I can instead run the vent up the wall and out the roof above the sink. Here's big question #1: the house is two stories with the kitchen on the first floor of course. Part of the the kitchen roof above the sink is actually a shed roof for the first floor only, and there's two bedrooms (and two windows) above the shed roof (sketch attached). Can I run the kitchen sink vent up thru the outside wall and vent thru the shed roof? Is there a distance it needs to be from the bedroom windows above? Or is a horizontal vent thru the outside wall ok, so long as it is above the kitchen window above the sink? Question #2: I plan to also add a peninsula with a prep sink (shown in sketch). I think the preferred way is an island vent that ties in to the outside vent for the main sink on the outside wall? Also read a bit on AAV's. But from what I've seen these are only permitted in NJ if signed off by an architect or engineer? I plan on doing most if not all the work myself. and in NJ the homeowner can act as his own architect/engineer (built my own addition a few years back and served as GC, engineer, architect and carpenter so I learned the ropes a bit). Let me know what you think! Appreciate the help as always. U guys got me thru the addition with flying colors! john p
