There really isn't much to do once you're set up and running. I haven't done so yet, but it would be a good idea to buy and install steel band clamps around the 5/8" diameter hose where it connects onto the hose barbs. This will help prevent any inadvertent slipping of the hose off the barb. If it did that in my bathroom, I'd have a 90 gallon mess to clean up!
Rain water does have some level of impurities in it. It gathers particles out of the air. It can carry with it tree and moss debris off your roof. The filters installed should gather most of the course stuff, but the fine particles may give the water a slight "tea" color. This is known as turbidity. The higher the turbidity, the most suspended particles are in the water. Given time to settle in your toilet's tank or bowl, these particles may accumulate. While these don't pose a maintenance issue as they are easily swept away with water current, you might have to brush your toilet bowl more often. The water is clean, and no extra chemicals should be used. Just give it a good brushing with a toilet bowl brush when needed. |
