Ryan, if you get a chance add a photo of your project in our photos section. We have plenty of room for new photos, now.

This project took me awhile to solve because I made it bigger than it had to be - as usual. I took the bedroom apart and ran a new, 40 amp fused +12v #8 gauge wire direct from the batteries. I terminated it in a custom enclosure under the driver's side bed with (4) fused links that light LEDs to indicate a blown fuse. I now have 4 separate, fused circuits under there with plenty of available power. One of them powers the pump with a #12 gauge wire and a 20 amp fuse. I installed a water leak detection system under both beds and put that on another of the circuits, leaving 2 more available for future use. Inside the aircraft bin storage up above, I pulled the backing panel off and found a large copper ground bar. I tied a new ground there with another #8 gauge wire and terminated that with a small screw-down bus bar under the bed near the new fused enclosure. I installed a relay on the existing pump circuit to flip power to the pump. While I was under there, I also replaced most of the flexible water lines, including the main line feeding the water tank. I installed a valve on the main line to make future plumbing work possible without draining the tank, and I removed the old strainer and installed the new Shurflo Extreme strainer I bought with the pump last year. Oh, I also put labels on the new circuits indicating their purpose & termination points so as to make it easy to service for any future owner, just in case I sell the coach some day. The system works GREAT now! In fact, the pump is running much slower and quieter while providing more pressure. I'm very happy. My next trick, to finish this up the way I want it, will be to purchase a second pump and tie it into the main system - I already made room for one next to the existing pump. I'll install a switch to flip a relay & select between the two pumps, so if I'm on the road and I lose a pump, I'll have a live backup at my beck and call without needing to tear the bed apart. As always, I thank the members of this forum for their valuable advice. Without you folks, I probably wouldn't have bought this great coach in the first place and if I did, I definitely would have a hard time maintaining it properly. I lurked here for a couple of years and this forum was a huge factor in my decision to buy a Wanderlodge vs. some other brand. -Ryan '86 PT-40 8V92 (Now with great water pressure again!)
