Loud water pump and possible solution?

I have my pump on a rubber "mouse" pad in addition to some braided washing machine hoses which are formed in a loop. Pump runs quiet. It is true like some have said that it is acceptable to have some "quiet" pump noise just to make sure it's working correctly.

I am a big proponent of a pressure tank. Why not have the pump cycle less and be able to run a gallon or two out of the faucet without having the pump going. I have a two gallon model (fits in an egg crate) and I don't think one would need anything bigger unless you had a whole bunch of extra space.

Be careful with the type of pump you run with a pressure tank. Some models have a bypass system on them that reduces flow just before the pump shuts off to ease any pressure bumps. I have found these very hard to adjust to work with my tank.

I run mine at close to 50 psi with no issues.





There aren't any winterizing issues nor will a pressure tank setup necessarily use anymore antifreeze than without a tank. When filling antifreeze you just run the pump, let the tank fill slightly, shut off the pump and then distribute the pink stuff through out the system. When it comes time to drain any liquid out of the pressure tank all that needs to be done is to turn on a tap with the pump off and the air precharge in tank will drain it out.

There is a lot in your post I question...

1. I don't see how with a 2 gal tank you will be able to run a gal or two thru a faucet w/o the pump coming on. You might be able to get like 8 or at most 16oz out of a faucet w/o the pump coming on, but not much more than that.

2. It seems obvious to me that it will take at least as much more antifreeze with a tank that is equal to the tanks volume over a non tank system. You have to fill up that tank if it's located close to the pump before any liquid will get to the lines, etc. Also, since the tank is going to be lower than most of the plumbing/faucets you will always have some water head pressure back on the tank that you have to overcome to get liquid out of the tank so any tank precharge pressure is not going to really help much.

OK ,I was just generalizing about how much water the tank will allow to discharge without the pump on. I have measured how much water I can get out of my setup without running the pump and it's come to around a gallon. In fact, this was optimized through several tests by varying the precharge pressure.

Secondly, I have enclosed a diagram showing the inside of a typical pressure tank. The first drawing shows what the tank and flexible diaphragm will look like when's it empty; ie, when the pump is off and a tap is opened. The precharge is going to push most of the water out.

So wouldn't it follow that while winterizing, the same holds true for antifreeze? Couldn't you pump a little bit in the system, shut off the pump then go around opening taps to allow the antifreeze to flow from the tank through the lines? Wouldn't that empty the pressure tank?
Let me know if I'm missing something...
