This is a tankless tank system. Has a Rinnai tankless attached to the 40 gallon water heater. Bring vinegar for this flush, and flush sediment out of tank. Radon below 2 picocuries. Sump pump is new. Tank flushed great, tankless did as well. No failing parts, water pressure is between 40-80. Leaks on plumbing lines and dialectic nipple. Customer reports water comes out of the shower head orange. Would like lead plumbers oversight or a follow up with the customer.
