I have a Fleck 5600 Timeclock Water Softener and was recently cleaning the brine tank when I noticed the the air check was broken into pieces. I ordered a new one, made sure I ordered one long enough so I could cut it to size, but the seller sent me one that is about 4" short, so it doesn't reach the bottom of the tank like the old one did. Does it matter, or will it still work fine? Thanks.
