Avoiding future problems with 370 is easy and cheap.

Contaminated and or high pressure water from a customer's can cause issues with the 370 or simular TMs.
This setup is like a Devistator filter for your fresh water if you don't have a fresh water tank setup.
This rainbird inline strainer/regulator has a 200 mesh filter inside and reduces the psi to 30. Ranbird has an additional coupling that could reduce the psi to 25psi if you wish.

But I had 100 gallons in my tank.

Idiots

Did you have one on your face? Naw, surely.

Here's another choice. $9 at amazon or Walmart, plus $2 for a screen hose washer.

PSI for residential is typically 50/60, this reduces pressure to 40/50. We have mostly had trouble at industrial buildings where the pressure can be 125 or so.
