MXBD1B-14C2 Manabloc Manifold

The Manabloc manifold is now made by Viega, but this model has been taken out of production. It is not designed to be taken apart and maintained; but, I split it open, cleaned and lubricated all O-rings, installed new threaded rod connectors, and torqued the assembly to perfect water tightness. Then, I found small cracks from old freeze damage radiating from the hot water supply... This entire assembly is now a paperweight.
