Re: Under Sink Filter
I thionk the galvanized water pipe is going to be a larger problem in the future than a clogged filter. What has been gradually happening inside the galv pipe is a rust build, like a clogged artery. It will be gradually building up until there is only a pinhole for the water to get through.
Yes, some debris was knocked free. But, you might want to also think of replacing all of the galvanized piping in the house. PEX is a good, cheap alternative, unless like in Texas the rodent like to eat holes into the water lines. Copper looks nice and takes skill to install (unless is is ProPress) but is more expensive and could also have problems if there is hard water.
Your under sink filter is just holding off on a larger problem.
Process of elimination. Good luck.
