Coach WaterPump Replacement Question?
I want to replace the factory water pump in my 2011 Coachmen Mirada. Waaaay too loud. Just doing a quick search on Amazon, turned up 3 potentials: $75.39 -- Shurflo Fresh Water Pump Model 2088-...

Three things you can do to your old pump to help....two are listed above. I like to mount mine on a mouse pad. It's durable, just the right size and is a perfect cushion for the pump. If the PEX tubing (hard plastic plumbing in your coach) is mounted directly to the pump, you need to do what Dutch recommended. The hard plastic line transmit vibration.
If you look under your sink in your home, you most likely have the chrome or white flexible tubing going to your faucets. This same tubing, available at Home Depot and Lowes has the same fittings as your water pump. It's typically a water hose fitting. If you get one of the flexible hoses (about 18") with the same female fitting on both ends, one will thread directly to the pump and you can use a threaded nipple to connect the two other female ends together.
Sometimes you'll get a banging noise (hammering), not necessarily near the pump, but somewhere else in the coach. This is the plastic PEX plumbing moving and hitting against a wall, making noise. You need to hunt this down and strap the plumbing down in that area, or cushion it with some foam.
Lastly, if you want a quieter pump, I've used the Flojet VSP (variable speed pump) for years. It only runs as hard as the amount of water needed. They're very quiet and my last one lasted the years I owned the coach.
If you add a larger, more powerful pump, make sure your wiring is of sufficient size or you'll burn up the new pump. The Shurflo products are susceptible to undersized wiring.
