Atlantic water heater's hot water pressure is significantly lower than cold water pressure.

Safety: Turn off power and close water supply before disassembling valves or fittings.

• Check faucet aerators and shower heads for debris; clean or replace as needed.
• Verify that any isolation valve on the hot outlet is fully open.
• If your installation includes a thermostatic mixing valve, disassemble and descale it according to the manufacturer's instructions.
• In areas with very hard water, scale can accumulate at the tank outlet; drain the heater and inspect the outlet fitting. Clean or replace as necessary.
