    Manabloc - severely restricted water flow
    Have an old Manabloc water manifold manufactured by Vanguard (now Viega.) Installed about 2008. Today, water flow from manifold is suddenly severely restricted; just a trickle.
    Water pressure to manifold is fine. I ran a wire (fish tape) up through water line, about two feet where water filter was located, up to intake (inlet) at bottom of manibloc. There wire stops, like there is a solid "something" blocking the inlet. Had initially suspected water filter system was shot, so tried removing it completely. The water pressure and flow is fine, but there seems to be some kind of obstruction at the inlet. Water is spring water, collected into a holding tank. Water is naturally soft, with no mineral buildup, but recently had been experiencing fine sediment. Completely drained and cleaned water holding (collection) tank yesterday, removed all sediment, and the water line to the manabloc manifold is fine. Any idea what could be causing the obstruction at the inlet?

    Here is a link to what the manabloc manifold looks like; file:///C:/Users/Cathleen/AppData/Local/Packages/Microsoft.MicrosoftEdge_8wekyb3d8bbwe/TempState/Downloads/tdpf_1218_manabloc_manifold_system%20(1).pdf

    Try blowing compressed air back through each line...see if that dislodges anything.
