Gunk in water filter

Filter keeps clogging up with gunk, I assume from winterizing then not flushing enough. Whats the best way to flush i guess bleach is involved...oh and I'm currently in Texas camping

If it were me, I'd use a bleach solution strong enough, so that I wouldn't wonder if it was strong enough. I'd remove the filter, since it is used for water that will be consumed. Then I'd put solution in the tank(s) and drive a bumpy road if possible to agitate it. An alternative is letting it sit overnight. Then flush and rinse, and agitate. The last step would be a new filter, every season.

I have some experience with filters, and they are tricky. If they work, they trap the bad stuff. The problem is next use, there is a tendency for them to flush out some of the bad stuff into the initial flow. The output could be worse than unfiltered, because the filter becomes a breeding ground. This is more likely with common charcoal and paper filters, than a reverse osmosis membrane.

Imagine the science project occuring inside a Brita type filter.

I drink tap water here in Denver, but I can appreciate carrying water jugs for drinking on the road. Someone said alcohol kills germs.

What sort of gunk are you finding in the filter?

Are you filling your tank with treated water? Next are you filtering the water going into your tank? other than flushing the system make sure your actually hooked up to a pressured supply so your not just draining and then refilling.

House hold tap water usually has chlorine in it so that is good to fill your tanks. Using well water or water from a filtered source, make sure the filter you use isnt removing the chlorine from your stored water.

Some people actually put access ports in their water tanks to be able to clean inside the tanks if they get funky.

Clean water is great, too clean water can get funky on you if your not careful.

I keep my water tank full all the time, I am not a fan of running around with empty-1/2 empty water tank. Warm untreated water and air space in the tank can grow on you.
