flextrol 2 bladder working?

Hello everyone. Need some advice and suggestions. Disclaimer: excuse the mess. Getting ready to paint, and lay down new kitchen tile. Sorry 😉 Let me preface this by saying I wouldn’t have the knowledge to do this myself. Just trying to get an idea if this is do-able before I pay someone to come out and look. I’d really appreciate anyone opinions. I’m getting ready to buy a new refrigerator for my apartment. Trying to decide whether or not to get a fancy one that has an indoor water & ice dispenser. I’m just not sure if hooking up a waterline is do-able from the layout of the kitchen. Waterline would have to be connected under the kitchen sink and ran to the other side. The washer is connected under the sink obviously. The new fridge would be where the temp mini fridge is. Is there a way for this to be done? Wrestling with how they would even conceal the water line? It would have to be routed pass the entryway. I don’t know. What do you guys think? Can this be done? Including photos

I'm on septic tank and once in a while would get a little sewer smell in the house that would seem to poor or linger in the hallway between bath and bedroom or in the utility closet that opens into the bedroom but it would dissipate fairly quickly. Summertime now and instead of firing up old HVAC decided to put in window units in bed and kitchen. At the same time, had to completely replace 50 year old septic system to new high tech, high maintenance ridiculously expensive aerobic drip system. SO...all is good but when I run window units, I get a horrible build up of stench. It's not immediate as it takes a few to 10 minutes before the smell begins to permeate everything. I thought it was the a/c unit itself so hubs removed and cleaned, sanitized both units then reinstalled. Smell still occurring. Called septic company - they said plumbing problem. Called plumber who went under house and said there was a vent pipe not capped so he duct taped it up and there was another plastic pipe that look like it broke due to settling but it had a rubber boot over it that had slipped, so he pulled it back into place and taped it up too. He left and all seemed okay until that night when the smell returned after running a/c. There's no smell in the attic - but there is a smell under the house but not all the time. The vent pipe that runs up to the roof...it actually stops short and then there's another piece of pipe attached to the roof for it. In other words, the pipe is to short to actually go thru the roof and there's about a 5 inch gap. Could this be the problem forcing the vapors to down draft somehow and the window a/c's are sucking in the air beneath the house? If I extend that pipe and put a charcoal vent on it, would that solve the problem?
