Some time ago I posted about issues with my tankless water heater, concerned about the water going cold mid shower.
Recently I found the issue isn't in the water heater - there are times when all the water pressure in the house including cold and at the closest spiggot to the mail drops by around half. It seems to be pretty regular intervals, roughly every 10 minutes.
What could cause this and how can I fix it?
Thanks for the responses everyone. There is a large recycling center fairly close by. It is likely the reason for the periodic drops.
I've adjusted the regulator. Although the pressure still drops it isn't nearly as severe.
Hopefully it'll be enough to keep the flow sensor on my inline tank from kicking off.
