I installed the 3000 system
I installed the 3000 system myself (homeowner) piping straight forward, pretty easy if you’re handy. Only problems I experienced was running piping through my outside concrete wall to connect to the main waterline entering house and dismantling the salt water softener contraption.
Water tastes better, ice is clear and dishwasher cleans glassware better.
Good product. Only comment is filter canisters would be better if they were clear so you could see if filters need to be replaced sooner depending on locL water sources.
