Domestic Well Water Tank

PostBy: coaledsweat On: Sat Oct 10, 2009 11:35 am

The plant has a brand new 85 GAL H2 PRO tank sitting here, it may not be used at all so I might be able to pick it up real cheap. Does it make sense to use something this big in your home? Are there advantages/disadvantages to having one this large? My existing tank is over 30 years old and I feel it may be on its way out. These seem to have some design advantages, the bladder makes no contact with the wall which reduces wear on it and limits exterior tank condensation.

The advantage is that your pump won't run as often thus giving it an easier life. The disadvantage is that as the pressure drops, it will stay low longer before the pump comes on. The cure is to tweak the pressure switch a bit so it comes on a bit sooner....lets say instead of coming on at 35 & shutting off at 55 PSI, you have it come on at 40....of course this makes the pump run a bit more often, but, still far less than with the smaller tank. Bottom line, if I had the chance to get a larger tank at the smaller tank price I'd do it.

Go for it. I've got a 86 gallon bladder tank. Pressure 40/60 psi. Works well. What's unique is the pressure switch is on the air side. No corrosion from my acid water. Same tank for past 15+ years, looks new. Piped with 1" PVC. Using a 6' tall pipe as a air hammer arrestor. Piped so it can easily be isolated and drained when it gets water logged. Reduces the need for hammer arrestors on the washing machine and dishwasher.

Tell me more about the air hammer arrester. I get a vibration in the pipes when the toilet approaches its shutoff point AND the water pump happens to be running at the same time. Sounds like it could shake the pipe joints apart!

I got the 110 gal Wellmate pro. All fiberglass with variable-pressure air bladder. 1 1/4" copper coming out. Pressure switch set for 30-50 psi. This tank can pull 50gal easy, at a time. I put a little extra air pressure in the bladder, so I only pull 35gal at one time. It's going to depend on what your pump's draw-down is, as to how much you can pull at one time. I have no noticable drop in pressure at any faucet, between the drop from 50psi to 30psi. No noticeable INCREASE in pressure, when the pump kicks in to refill to 50psi.
I like this setup.

the vibration in your toilet is from the diaphram washer in the ball cock either replace it or the whole fill valve it has nothing to do with your well pump or water hammer arrestors or lack of them

Just a caped length of 1"PVC plumbed in the cold water supply line after the well water tank. The standing column of air acts like a shock absorber. Over time the air will be absorbed into the water reducing its effectiveness. Then you isolate and drain the water in the vertical column. Pressurize with air to the low pressure setting on your pump and re-connect to your system.
