Small round bulb w/ schrader valve ???

On our, new to us, '01 30' Excella I see next to the water pump a round bulb approx. 4" d with a schrader valve on the top. From my limited knowledge of plumbing I might think this is a device to stabilize the flow when using the pump. Not sure, just a guess. But could any of you AS Guru's out there tell me just what this is ??? I winterize by blowing the lines using an air hose at the city water inlet. Does anything special need to be done with this or will it blow out with the rest of the system ??? After blowing I disconnect the
inlet / outlet lines at the pump.

Thanks all, See ya on the road sometime.

I forget the exact name for it, but it's basically a pressure modulator to keep pump pulsations from the faucets....just like you assumed.

Don't believe you need to do anything with it when winterizing.

Thanks Steve. Appreciate your help.

Bye-the-way, is Common Sense, Texas something similar to Normal, Ill. I certainly am in Abnormal, NJ and not sure if there is ANY common sense here. That's for sure.

It sounds like an accumulator tank. They are pressurized, hence the Schrader valve, and provide an air cushion that smooths the water flow from the pump.

My submission or possibly misnamed places is Humble, Texas. Just doesn't sound right somehow.

I think that's why they pronounce it "uhmbull".

Somewhere in the manual should be the following, it's the Accumulator Tank used to smooth out pressure and reduce pump surging.

I'm sure that if I read the manual it would have answered this question. But the manual is in the trailer parked at my son's house. Thanks all.

Hey Vaughn, do the make pie in Humble, Tx ?????

You won't find "Common Sense, Texas" on the map. Just a little "thing" with me.

That's the best place to live. Somewhere that nobody can find you unless you want to be found. I like that.

Humble, TX was probably named for an oil company, mergers turned it into part of Exxon/Mobil years ago.

It was. I remember Humble Oil.

I still enjoy it, though.

On the other hand, there is Texico, New Mexico that has noting to do with Texico the oil company, which is from Beaumont.
