SEE REPLACEMENT PART: OBSOLETE

The Hydro-Quip 5.5kW M7 Flo Thru Heater [PS-B Series] [L-Shape] [230V] [60" Cord] is a practical replacement choice for pool and spa service work where fit, connection style, and application details matter. This Hydro-Quip item is associated with Heaters and is selected for heating system when the existing part no longer performs as expected or when a system rebuild requires a correctly matched component. The listed configuration includes PS-B Series, L-Shape, 230V, 60" Cord, making it easier to compare against the original part before ordering.

Part number 48-PSL55-B should be matched against the existing component, owner’s manual, or equipment label before installation. Use this part when servicing heater performance issues, replacing aged components, or rebuilding a compatible assembly where water flow, electrical rating, and housing layout must line up correctly. Because heater parts can look similar across different brands and model years, confirming kilowatt rating, voltage, plug style, manifold size, or sensor requirements is especially important. For best results, inspect the surrounding seals, unions, gaskets, screws, or mating surfaces during replacement, since related wear can affect performance even when the main component is new.
