New Shallow Jet Pump and Pressure tank…inconsistent water pressure

[Snot81]

I’ve had this issue of inconsistent water pressure at the shower specifically for last 15 years. I recently replaced my shallow well jet pump and upgraded pressure tank to 36 gallons……
The problem is when I shower pressure slowly drops until pump kicks on at 30psi then pressure is great when it shuts off at 50psi. Is there a way to get more consistent water pressure specifically at my shower?

Lol! You must be new here. Welcome! A search on this forum for anything about low water pressure will bring up hundreds of others that have had the same problem. A Cycle Stop Valve will work fine with your large tank. But a 36 gallon size pressure tank holds 8 gallons of water and the CSV cannot deliver strong constant pressure until the 8 gallons has been used and the pump is started. The CSV will also work fine with a 4.5 gallon size tank. Then you only have to use 1 gallon before you see the strong constant pressure from the CSV.

How much pressure can the pump build? If you increase it to 40/60 that will give you 10 PSI more pressure.

A flow regulator for the showerhead can make the flow more consistent. This can be built into the handheld or showerhead, or the regulator cartridge can be in an inline adapter.

Neoperl is one brand of regulator elements.

But for sure the CSV can make your shower pressure much more consistent for those long showers.

Looks like an SNE pump. Those can make about 65 PSI max, so I wouldn't turn up the pressure switch more than 35/55. A regulator after the pressure tank or on the shower head always reduces the pressure. Can make pressure more consistent, by making it consistently lower. No matter the pressure setting, when the system is on the low side of the pressure switch setting the pressure will be low, and even lower on the outlet of a regulator..

Thank you this input….I do wish I knew about this Cycle Stop Valve before I got my tank because that’s an expensive device. My last pump a Simer 3/4 convertible shallow setup with a 20 gallon tank. It would cycle once for showering and not be able to shut off on a 30/50 pressure set until after shower was complete. That pump lasted 8 years opposed to the prior pump only 4. So I assume it was like are ad says the constant cycling. Would it also be true I would have to move the regulator from the pump to after the Cylce Stop Valve?

Yes, the pump that didn't cycle during a shower lasted longer because it was not cycling on and off. However, it probably only lasted 8 years because it was working too close to its deadhead or max pressure. If you adjust the cut off pressure close to the pumps max pressure it can keep the pump from cycling at low flow rates. But if it isn't cycling for a single shower, it is working so close to deadhead pressure that it isn't pumping enough water to stay cool when the shower is turned off. It probably filled the pressure tank so slowly to 50 that the pump was getting hot.

The CSV kind of works the same way to prevent cycling, but it works way below the pumps deadhead pressure. So, even low flow conditions like to fill the tank is enough to keep the pump cool.
