A new pump is on my list. Plus the plumbing from tank to pump is all corroded and needs to be replaced anyway, and yes, an easy drain valve and an antifreeze suck port is in the design too.
At the moment planning on the ShurFlo 4008 (3.0 gpm 55psi). Looked at the Whisper King, but it only puts out 2.0 gpm at 30psi, which isn't even as good as the OEM ShurFlo 200's 2.8 gpm. The 4008 supposedly is designed to be quiet, but anything is bound to be better than the 200 I've got which is Very noisy.
One addition I'm looking at is an expansion tank per previous discussion. Don't seem to have one in the coach at the moment, unless it's hiding behind the bathroom, and it seems like it would give a great improvement in constancy of flow and less pump cycling. The one I looked at at HD was a Watts DET-5 for $39. A bit confused because the Watts website says the model is obsolete, but HD had two new ones in their orig boxes. I know exp tanks aren't needed in the more expensive constant flow pumps or ones with internal bypasses, but the 4008 is pretty basic without all those bells & whistles.
Also wondering how much an exp tank might really help. Info says it's for handling pressure fluctuation from hot water heating/expanding. Do they really give much benefit ($40 worth) in our systems?
Thanks,

> While you are upgrading the plumbing, consider upgrading the pump itself for a quieter model. Also, I have eliminated the fill port on the tank by mounting a valve from the side that is pressurized when you hook up to city water that goes to the tank fill spot. My drain valve is accessible from under the coach. I also added a line on the suction side of the pump to fill the system will RV Pink antifreeze.

Jay,
I'm a strong believer in accumulators. If large enough to fool with
(like the HD model you're considering), they completely eliminate flow
surges; save start-up cycles of the pump, improving its motor's life;
and, usually prevent disturbing HER when I visit the bathroom in the
middle of the night.
I wouldn't bother with one of those softball sized ones though.

I'll second that. One of the things to do after you install it is to set the air pressure in the tank. Set the air pressure 2 PSI below the turn on point of the pump. This will give you the maximum capacity of stored water in the tank. Every time I hear someone without an accumulator tank starting and stopping the pump while trying to run a faucet, I suggest they install one. It makes things a lot nicer and sure saves the cycles on the pump. Get the small one from HD used normally used for a hot water expansion tank. I'm guessing they are about 14"in diameter by about 18" long.

Why bother, The accumulator works and there is no need to replace the pump until it goes bad. My pump only runs occasionally because of it. A little lesson from water well pumps. The larger the accumulator the longer the pump lasts. A water (deep) well is rated in cycles and not how much water it pumps. The same applies here. I do not understand your aversion to having an accumulator with a couple of gallons capacity. You can install it anywhere that you have a cold water line available.

I selected a FloJet SensorVSD pump. It has a variable speed motor. It is definitely quieter than the one I took out (which pumped but never shut off). But this is not as quiet as a Whisper King.
The nice thing is the variable speed motor means it is pretty quiet when only using a little water (such as flushing toilet). It does get a little louder when running a faucet for an extended time. But again it is still considerably quieter than many pumps I have heard.
Also the variable speed motor gives constant pressure without the need for an accumulator pump.
I suppose the valid points Ken makes about the start/stop cycles still apply. But so far I am happy, and I did not have to find a place to plumb to plumb in an accumulator tank.

Just wondering where I would find a larger accumulator tank? Just caught
that part of your conversation and sounds like a great idea. Info would be
greatly appreciated, thank you

Yes, HD hot water heater section. Also called an expansion tank. My store had two, both WATTS brand, small one DET-5 for ~$40 and larger DET-12 for ~$65. Watts website says both are obsolete. Get them while stock lasts, though they may have a newer replacement model, didn't research it.

You can get these in various sizes up to at least 50 gallons. They are used for residential and larger water well so the well pump dies not have to run as frequently. The small one I recommended is used primarily as an expansion tank for hot water systems.
Go to Home Depot, Menards, Lowes, Ace, or any place that supplies plumbing for home water systems.
