Product details

The Hayward HAXBPK1932 is the new style bypass kit for H-Series, ED1 and ED2 heaters built after 10-28-2000. It arrives complete: the black plastic baffle, the round plastic bypass end, the stainless bypass shaft and plug, the bypass spring, and the HAXHOR1930 header o-ring.

What the bypass does

Not all the water going through the heater needs to pass across the heat exchanger. The bypass diverts part of the flow so the exchanger sees the right amount, which protects it from thermal stress and keeps the outlet temperature under control. The flow control thermostat sits in the 1-3/8 inch hole in the rounded end of the baffle.

Old style or new style

This matters more than the part number. The new style baffle is the longer one, with the single large thermostat hole and two 5/8 inch holes beside it, and it carries 0101421101 molded into the bottom face. Heaters built before 10-28-2000 take a different kit with brass fittings and a shorter baffle with two holes in total. Pull the old assembly and compare before ordering.

The o-ring

Because the header has to come off to reach the bypass, the header o-ring is in the box. Fit the new one rather than reusing a compressed o-ring that has been in service.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heaters take this kit?
Hayward H-Series, ED1 and ED2 heaters built after 10-28-2000. Heaters made before that date use a different bypass with brass fittings and a shorter baffle that has only two holes in total.
What comes in the kit?
A black plastic baffle, the round plastic bypass end, the stainless bypass shaft and plug, the bypass spring, and the HAXHOR1930 header o-ring.
How do I tell the new style from the old one?
Look at the baffle. The new style is the longer one, with a single 1-3/8 inch hole for the flow control thermostat and two 5/8 inch holes next to it, and 0101421101 molded into the bottom. The earlier baffle is shorter with two holes total and brass fittings.
Is the header o-ring included?
Yes. The HAXHOR1930 header o-ring is part of the kit, so you do not have to buy it separately when you open the header.
