Built new two story home 10 years ago with 75 gal water heater, built-in water softner and connected to 45psi+ city water supply. Have recently had cycling water pressure/flow that lasts for hours then returns to normal pressure/flow. Called city water and no ideas; neighbors on same supply line and no problems. I susspected the water softner and bypassed, but to no avail. Still have problem at all outlets in house, including toilets. Would appreciate help, thanks.

 

Hi:Jack415

I am assuming here that this cycle is happening during the part of the day when house demand is highest? You didn't mention when your noticing this problem.

Have you noticed this problem when the water softener happens to also be back flushing?

Just a thought, since back flushing is a high water demand cycle, it may be all or part of the peoblem.

Try altering the back flushing time to late nights and see what happens. Check the valves on the softener for the correct positioning too.

You should also try turning off the conditioner and see what happens.

Most water meters may have built in pressure control valves. Yours may have a defective one that acts up sporadically. You may need to have it rechecked.

Good Luck
Tom
