This vent is to allow pressure equalization across the regulator diaphragm and ANY propane leak here is an indication of regulator failure.  I would recommend turning off the gas bottles immediately and getting the regulator replaced before turning them back on.  The diaphragm could rupture at any time and generate a real serious (read large) leak that could lead to bad things happening!

Dutch, great ides.  I never looked to see what connections existed.  What a happy coincidink that they are the same.

Hey all-  I am going to replace our water pump and want to install an accumulator tank.

Tank: I am tied into this type of tank:  

https://www.lowes.com/pd/Utilitech-2-Gallon-Vertical-Pressure-Tank/1038561

And have some fitting/winterizing questions.  I was thinking that I want to T that in to my water line, and go valve, union, valve, tank.  This would allow me to remove the tank for the winter, while not spilling water all over the place.  The valve on the system side would allow me to glycol in the fall (and spring bleach/flush) without the tank in.

Question - what do others do, regarding these tanks and glycol?  I was thinking it would be a freeze hazard, as it will be installed on its side so nearly impossible to drain well.  Removing it I can fully drain it and safely put it in the basement.

Question - any recommendations on piping, valving, unions to make these connections to pex?  I have never worked with PEX, easy DIY options for connecting to this new T?

Water pump-  Ours is nearly 20 years old, so as it is weakening I am just going to replace it.  Recommendations of make/model?  How about easy to purge inlet filters (we get a lot of debris in our well water/piping system at the house).  Existing pump is a Shurflo 2088-403-144, 2.8 gpm.

Also, any recommendations on a product to use for an outlet loop on the pump for noise?

 

Thanks so much!!!

The tank you listed, and most of this type, use an internal pressure bladder.  When the tank is emptied, the bladder is still under pressure so it drives out virtually all of the water.  I would only worry about the small amount of water in the lines after it is drained, that would be the only water that could freeze.

This type of fitting Tube fittings can be used easily to connect/disconnect, just watch sizes.  Normally PEX requires special fittings and crimp rings with a special tool to do the actual crimping, expensive!

Won't comment on the actual pump, several good ones available, look for 4 chamber models.

A loop of soft reinforced tubing at inlet and outlet plus placing the pump on a pad (carpet remnant etc.) will keep the pump quiet.  Consider putting in a winterizing kit at that time also.
