I installed a CSV1 as part of an almost complete overhaul of the interior portion of my water system (new smaller pressure tank, new filtration, new pressure switch & gauge, new hot water heater) when I had my geothermal system installed in October 2011. Money was getting tight & I wanted to try out the CSV, so I didn't spring for the CSV1Z. The CSV1 is now weeping (judging by what my filer looked like pre-CSV1, I'd say there's some debris in there). I hope to replace it with a CSV1Z before the winter (finishing up some other project$ around the house), but in the meantime, can I pull the CSV1 out & clean it...if so, how do I go about cleaning it? Thanks.
