The thermo stress that causes the T&P to relief is putting a lot of strain on this tank and will make it prone to failure much faster.
If just lowering the incoming pressure can stop excessive velocity and not forcing the piping to work at Max pressures think of the possibility of this valve not working JUST ONE TIME.
Having these SAFETY devices acting as operating controls is not in the best interest of the clients.
This isn’t just digging a hole and planting a box for sewerage this is a serious trade we are in and pressure uncontrolled can kill not to mention the very real possibilities of someone being scalded
Unlike others. WE ARE professionals and safety and health is our main priority.
