Follow-ups Remote controls for water pump, heater, reefer.Re: leaking at holding tank door leaking at holding tank door January 02, 2024, 11:47:31 am Hello!!Yesterday I emptied my holding tank to half, hooked up to city water, and in the morning discovered a huge amount of water on the ground below holding tank door and stream going to street.The wall of the rig at the holding tank door was striped with water still running down it! I know it sounds obvious the holding tank must have been full… yet… I had just spent 2 months parked with city water hooked up and the holding tank full! Before I headed out yesterday to new location, I dumped half the water in the holding tank to lighten my load…. and today I woke up to find water from holding tank trickling down wall of RV .What caused this… any ideas.I might as well throw in that while driving here, I turned on my water pump in the rig and water came out the faucet, but would not fill the toilet. Is my rv mad at me for moving it!!!😵💫Yikes!Thank you,Lynn

Re: leaking at holding tank door Reply #3 – January 02, 2024, 02:06:03 pm I know this has been said before, but... many of us never connect to city water. Instead, we fill our freshwater tank, draw from it, and refill as necessary. The advantages:1. Water in the tank is constantly refreshed, instead of going stagnant.2. In cold weather, there's no risk of your water hose freezing.3. In warm weather, water in the hose doesn't sit in the sun growing nasties.4. The hose isn't out in the open where it can be gnawed by rodents.5. There's no risk of your plumbing being damaged by excessive pressure (yes, you can use a regulator, but they're not always reliable, and they restrict the flow rate).6. You never have to worry about the pump valve failure described in the video.7. You never have to worry about the valve at the city water inlet failing (another common cause of this symptom). 5 Likes
Re: leaking at holding tank door Reply #4 – January 02, 2024, 07:42:52 pm A question, why would you dump only half of the holding tanks and not all of it? Just wondering.Andy’s suggestion to never use the city water connection is great advice, RV park waters systems often suffer from pressures strong enough to damage your LDs plumbing.Our LD’s city water connection was capped when new, 21 years ago and has never been used.Do consider carrying a replacement water pump, preferably the same as what is presently installed, to ease a potential on the road install.Larry 2 Likes

Re: leaking at holding tank door Reply #6 – January 03, 2024, 12:48:15 pm "And if you can remember to switch off the water pump when you leave..."Make it a habit to turn off the pump as soon as its no longer needed. Easy on, easy off. Then there's no regrets later!
Re: leaking at holding tank door Reply #7 – January 03, 2024, 02:12:38 pm "I still think there should be a water pump switch by the door."That would be good. A switch in the bathroom would also be nice--then you could leave it off most of the time and only turn it on when you need it (bathroom or kitchen).
Re: leaking at holding tank door Reply #8 – January 03, 2024, 02:53:33 pm Two-location switching for 12V is fairly common. This past Summer I worked back-and-forth with a Winnebago owner as we figured out how to install a second water pump switch in his coach's bathroom. I found a diagram that extended that design to a third water pump switch. Ordinarily, once you go beyond two switches you install a water pump controller (link here), to simplify the wiring.If someone wanted to go down this road, I'd be willing to forward the info I have to him/her, and maybe advise on the project.Mark H. 1 Likes
Re: leaking at holding tank door Reply #9 – January 03, 2024, 05:32:07 pm I've had several rigs with multiple water pump switches (kitchen, bathroom and the outside wet compartment. They all used latching relays as in Mark's link. Real handy. Good project for our LDs!jor

I found a diagram that extended that design to a third water pump switch. Ordinarily, once you go beyond two switches you install a water pump controller (link here), to simplify the wiring.I used a different approach to avoid running wires to control the water pump from the kitchen, bathroom, and cabover bed: a relay controlled by small "key fob" transmitters that switch the relay on and off. The relay module mounts near the water pump; I mounted each transmitter fob with double sticky foam tape in a convenient place in each location. The $20 unit comes with 5 fobs.DieseRC 433Mhz Universal Wireless Remote Control Switch DC 12V 1CH RF Relay...But why one in the cabover bed area? I like to turn off the pump at night, but often don't think of it until I've crawled into the cab and snuggled into the bed! 2 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

Re: leaking at holding tank door Reply #12 – January 06, 2024, 03:47:20 am I must be the maverick! I turn the pump on at the beginning of a trip and leave it on until I get home. Sometimes I forget to turn it off until I dump my tanks at home. And sometimes I'll find it still on weeks later! Maybe I'm courting disaster, but I haven't accidentally filled up my tanks, or soaked the wood floor yet. After about 20 years I did develop a leak in my pump, and it's 'thumping' alerted me to it. Ended up having to replace the pump. (the seals were leaking a bit). [Thanks Kent for having a 1/4" socket set that I could use] I have PEX A plumbing. Thanks Eric, a nifty looking low cost remote controlled relay. RonB 2 Likes

Re: leaking at holding tank door Reply #14 – January 06, 2024, 01:08:11 pm A similar design, that I bought all the parts for, was a timer module (maybe $8) that would shut the water pump off after about 10 minutes (user selected time). That could be coupled with Eric's remote RF switch and if you forgot and left the rig/or fell asleep, it would turn it off automatically. You could wire it so the normal switch would still override the timer for shower time. Here is a fancier version of the timer I was going to use. Timer WiFi 10 AMP 6V 12V 18V 24V TIME ON Off DELAY CONFIGURABLE, Cycling and... I had contemplated using the timer to shut off the small noisy exhaust fan in the bathroom, but I replaced it with a Fantastic fan, and I can't forget that. Another use for Eric's remote switch could be turning off the refrigerator when getting gasoline. I have forgotten, a few times, to turn it back on. The remote could be at the driver's seat. Indicator light on the dash to tell you the refrigerator status, green on, red off. You'd need to run a wire to do that.

But in a space as small as a LD just how difficult is it to hit the WP switch, either on or off, only when needed? Seems like a solution looking for a problem! We have a TurboKool evaporative cooler that gets it's water from the coach system, requiring the pump to be on. But, if we drive somewhere, the sloshing in the cooler will cause it to overfill, and water starts running off the roof, down the sides of the MH. So, we usually stop, go back to the bathroom, and turn off the switch. Now, we just tap a fob while driving - life is better! Also, if we forget to turn off the pump on a night when we use the cooler, the pumps runs intermittently to keep the cooler reservoir full. That's not needed at night, as the cooling required is much lower. Before I had to crawl out of the cabover bed, go to the bathroom to turn off the switch, and crawl back into the cabover; now, I just tap a fob - life is even better! I'm intrigued by the "auto turn off" idea, but with a fob always within easy reach, I don't think I'll pursue it. But, if you want to go nuts, the relay unit supports 20 fobs! 1 Likes
