Um, question. So on all my faucets the part you twist out is inside the part where the water comes out. I can unscrew the part from the faucet but the part I attach the adapter to is inside the faucet. Anything else I can do?I started with one of these cheap ones and quickly upgraded. I'd say anything 40g and up get a better one. I went with the BRS 5 stage and love it. Easier to see when filters should be replaced, flush valve and built in TDS meter are well worth the extra money.
