While redoing my plumbing to include having my Clearsourse filter now plumbed behind the panel I noticed a leak on one of the hot connections into the panel itself. I snuggled it up and all is good, but wondering if anyone else sees an increase in water pressure when turning on the hot water tank.

Having set my water pressure gauge to @55 and then after water heater warmed up saw 120!

This same scenario I always get a high pressure surge when turning on a spigot. This is the 1st time I noticed the spike.

Usually I have the pressure gauge on the outside faucet feeding the rv. I have since moved it inside due to the cooler overnights once in awhile.

My set up is: water hose to nautilus panel-line out back into filter-and on filter out I have the pressure Guage then hose going back into nautilus panel.....

Normal?
