I have had my scwd running for less than a week and the flow keeps getting stuck to one outlet. I have to hit the scwd with a hammer to get it to flow in both directions. It started with just once a day but I had to do it 10 X today already. I guess Ill take it off to clean.
I have SQWD on my return to my 170. I use a foam prefilter on my mag pick up. I have been using it for over three months and it has worked flawlesly. A little care and it will work great, just use some prevention and keep the junk out.
