My cottage (year round) currently has a line going out to the lake (its got a heat trace line in it), the water enters the crawlspace and then goes through a 5 micron filter and then the big blue thing before it is sent off the the rest of the house. The problem (issue) is that the outside spigot that I use to water the lawn takes water AFTER the water filter. I want to T into the pipe before the filter (somehow) so I can have an endless supply of water for the lawn or whatever. But that doesn't result in an early death for the water filter since I don't really need the fish poop filtered out for the lawn I really have no idea how this set-up works but there is one hose already hooked up at the T that goes to (and from?) the blue tank and there is another hose bib at the end of the pipe that goes out to the lake. Can I attach the one at the end of the lake supply hose (red handle) to the exterior hose bib or will that make water run the wrong way through the filter?
