Earlier today I noticed my Hayward Heater (H400FDN) has a pretty steady leak, see video. I pulled the heat exchanger and plastic manifold (Series Front Header Assembly), but can't find any cracks in the manifold plastic. Also, if the exchanger is leaking then the leak would be deeper inside the heater. It appears the leak may be coming from the flow (oval) water redirector that basically takes water from one tube and shoves it back into another tube (see pics below). It doesn't have any bolts, and relies on pressure from the manifold to hold into place.
Has anyone seen a leak from this plastic water redirector before?
