Question...on our 2552, the water pump has been working fine for a bit more than a year. A couple of trips ago, it still worked but there was a sudden increase in the amount of vibration and noise from it. It still pumps the same but the vibration is not good. I checked and it is still solidly mounted. I've assumed it may have lost an impeller blade or otherwise has an imbalance leading to the high vibrations. Have others experienced the same?
The plan is to replace it at the end of the season given that it still pumps water and we have only one weekend trip remaining before we winterize. Does the water tank in the 2552 need to be drained before replacing the pump? I don't think there is a valve between the pump and tank so I'm thinking that is the case.
Any other words of wisdom? We already purchase 2 pumps, one replacement and one spare.
Yes, drain the tank. It, along with the water pump are under the passenger side bed.
Yes, there is a drain valve on the water tank. It's on the center, bottom right side of the water tank when viewing from the walkway between the twin beds. It's a quarter turn valve that feeds the water out a short PEX line that goes through the bottom of the RV and drains the water. It works similar to the low point drain valves beneath the bottom drawer in the kitchen.

You normally just lift the cutout cover under the mattress and reach down to turn the tank drain valve to empty the fresh water tank. But in this case, you have to remove the under the mattress plywood to replace the water pump anyway.
