Squeeky Door & Filters

We have three filters under our sink. We change #1 which is this one, on the left every month with the the one on the right. We change # 2 (not seen every other month) and # 3 once a year. Because of the drippy faucet in our tub the inside of the tub under the faucet looks this color so I have to clean it often to get it white. We buy water or Elder Williams fills a bottle with the filtered water which is good.
Boy am I glad I took this video. We have been hearing this sound, which echo's because this is not a through street, for almost 6 months now. Well, Elder Williams found some lubricant spray and went down and lubricated the hinges of this door and also the door to our building. It's so quiet I thought the world had come to an end.
