Second the old tank uses a 1” npt connection. The tank I want to replace it with has a 1 1/4 connection.
What should I use to connect the new tank? 1 1/4 pipe and some kind of adapter?
Thanks in advance for any advice.

Do you have a jet pump, or a submersible pump? The reason I ask is that you have your pressure switch connected remotely, which is OK, but I would usually associate with a jet pump. You have a check valve into your tank tee, and I would be considering eliminating that.
Yes, you can adapt up from 1 inch to 1.25 inch.
View attachment 63920 View attachment 63921 Hi. I want to replace my failed pressure tank with a larger one and need some advice. First the ball valve is cracked and leaking. In order to remove the valve should I sweat the fitting off the copper pipe or should I cut the copper pipe and solder on a new fitting once a put on a new valve? Would using some kind of union be better to make replacement of the tank easier in the future?

A single union would not have helped change the valve or the tank, unless there is a lot of play in pipe to the left.Thanks for the replies. I’ve decided to cut the copper pipe and install a union. Copper to copper. I’ve soldered copper fittings before and I like the permanence of a soldered joint.
There is no way to cause a short cycle with a CSV, even with a small tank. The 4.5 gallon size tank holds 1.2 gallons of water the same way an 80 gallon tank only holds 20 gallons of water. With the small tank, you must use this gallon of water before the pump will come on. One gallon is more than needed for an ice maker, or to wash a toothbrush. The CSV fills the tank at 1 GPM, so a tank that holds 1 gallon of water is a 1 minute mechanical timer. After flushing a toilet, the CSV will keep the pump running for another minute. If you flush again, the pump just stays running and the 1 minute mechanical timer restarts after every flush. So you could flush a hundred times in a row, and the pump would only cycle once. In the same way, after you flush you have a minute to wash your hands, then another minute to wash your toothbrush before the pump shuts off. If you brush within a minute the pump will still be running when you rinse and wash the toothbrush again. If you get into the shower within another minute, the pump is STILL running and stays running for as long as you are in the shower. If you dry off in less than a minute, the pump is STILL running if you want to flush, brush, or use water again for any reason. Basically, the CSV makes sure you are finished using water as it is refilling the little pressure tank, before it shuts off the pump. Then you have 1 gallon in the tank to use before the pump will start again.
With the CSV and small tank, you wouldn't even be able to make the pump short cycle if you tried. You would have to close all faucets and wait for the tank to fill and the pump to shut off. Then if you turn on a 1 GPM sink faucet, the tank will supply water for 1 minute before the pump comes on. If you immediately close the faucet again, the tank will refill in a minute and the pump will shut off. By waiting for the pump to shut off and immediately opening the faucet again, and doing this over and over, you still can't make the pump run less than a minute, or be off less than a minute, so there is no way to make it short cycle.
If you run more than 1 GPM continuously, the CSV will keep the pump running continuously (no cycling). If you run less than 1 GPM, as in 0.5 GPM continuously, the tank will drain in 2 minutes and the CSV will refill the tank in 2 minutes, which is a cycle every 4 minutes, which is not short cycling.
Yes an 80 gallon tank holds 20 gallons of water. And no it is not too big to work with a CSV. The CSV will work with any size tank. But with the big tank you will see the shower pressure decrease from 60 to 40 for the first 6-8 minutes, where as with the small tank it will see a strong constant 50 PSI before you get the temp adjusted.
I know it is counter intuitive, but the CSV and small tank will give you better pressure, cycle the pump less, and save a lot of money and space compared to the big tank.
You may have another 20 years in that pump.My pump is 24 years old and still working great but I know its near the end of its life (Franklin motor and Goulds pump head)
So I assume my 80 gallon working tank would have to be replaced in well house to a smallwer tank? I already have a smart grunfus reculator pump for instant hot water and all showers have moentroel non scalding valves-instant backup power generator so power is a non issue. what tanks size is optimal-we are two users in the home-well is 160 feet away downhill slightly about 15 feet so some head pressure is lost at 60#s on the 40-60 psi cycle.
My pump is 24 years old and still working great but I know its near the end of its life (Franklin motor and Goulds pump head) I hear the new one in all brands last about 10 years now. the CSV would extend that life some.
This is awkward, but...
