Kind of new to self servicing our home's water systems. Water quality has been great but one thing about the greensand filter has me wondering. The current setting for the Brine Draw cycle is for it to run for 1 hour. However, the actual draw of the potperm lasts only like a minute and a half, then I hear a big clunk (I think from the brine tank valve closing) and the draw from the tank stops. The tank itself looks fine otherwise, from what I can gather from research it appears to hold the correct amount of brine (water line being about 3/4"-1" above felt). And I can actually feel it through the line that it is pulling the chemicals during that minute and a half or so. Still, it just runs for the BD cycle for the rest of the hour, and I don't see much purple come out the drine line during this time, but the water is much clearer.
What confuses me further is that years ago when we first installed it, the system didn't seem to be so quick to pull all the potperm from the brine tank, and the drain line would run real purple for a bit until it flushed everything out during the full BD cycle. That made it feel like it was doing a more thorough job then than it is now.
So my question is, is this minute and a half of draw from the brine tank normal? And if so, is keeping it set to one hour for the whole BD cycle still good just to make sure any excess potperm is flushed from the system?
If it is not normal, could it be the BLFC flow is too much? I think it was replaced at some point. Looks like what's on there is a 1.5 gpm BLFC
Thanks everyone.
PS - also if it helps, it's a 10" tank with a Fleck 2510SXT head
