  1. Water Pump squealing noises? When I rev it up to 3000 rpm or sometimes before it shifts into 3 rd gear it squeals but not always. Wondering if anyone tips on when to change to do? I just drove back 2700 miles with no trouble but now that I am home I am trying to find things to fix. Bored eh!
  2. Are there causes for the coach water pump cycling when the system's not in use (no tap open, not flushing toilet, etc) other than leaks in the system? My pump does this somewhat intermittently. For instance, about 90% of the time, within 30 seconds after I've closed a tap or completed a flush, the pump will give one very brief grunt. About 50% of the time, between 3 and 5 minutes later, it'll give another grunt. Sometimes, but rarely, it'll grunt again 5 minutes later. After that, it doesn't happen again. I can (and have) leave the pump on all night and it won't grunt again. If its has its first grunt or two, I can turn it off over night and it won't grunt again when I switch it on in the morning. Other than one short section that runs behind the fiberglass bathroom unit wall, I've checked all the piping and connections and they're bone dry. I've checked the drain tubes coming from the system drainage valves, and they'd dry. I've checked the pump and the floor under the pump, and it's dry. I have checked the plumbing going into the water heater, and checked in, around and under the compartment it's in, but I haven't pulled the heater all the way out. I'm stumped! I did drain the system last year, is it possible there's an air bubble in there somewhere that's causing this? I've used all the taps since then.
  3. Hey y'all, hope today is treating you well. Just picked up a Sunrader yesterday and I'm stoked! She's in pretty good shape for being 32 years old. Right now I'm trying to troubleshoot some issues with the water pump and plumbing. When I turn the water pump on, it will run until it has built up pressure (I suppose?) and then stop. Then as soon as I turn the kitchen sink on it kicks on again. If that's normal, cool, but I really have no idea since this is my first RV of any kind. But what doesn't seem normal is that it will at times shut off and I get no flow out of the sink. I'll flip the switch to off again, wait a while, then turn it back on and it will work, with water coming out of the kitchen sink. The hot and cold work on the kitchen sink, but only the hot on the bathroom sink and it doesn't seem like the shower works. The folks I bought it from winterized it and I seem to have run most of the pink antifreeze out of the cold line, but not the hot line. I left the sink running on hot (not sure if the water was actually hot) and it was quite pink. I opened the door to the bathroom and saw some pink bubbles coming up from the shower drain, as shown in the picture below. Could it be that the black water tank is full? Or the gray water? I don't think I ran THAT much water through the lines.... Thanks for your help!
  4. So I am replacing my water pump on my 91 V6 3.0 and bought the NAPA water pump and then ordered the AISIN water pump. I took a quick video so you could see the difference. <iframe width="420" height="315" src="https://www.youtube.com/embed/_ZhuXTsXOK4"frameborder="0" allowfullscreen></iframe>
