Review on Enhanced Delta Faucet R10000-UNBXHF MultiChoice Universal Shower Valve Body for Shower Faucet Trim Kits by Ricky Mayo

Purchased a year ago for a bathroom renovation while renovating a house I bought. I started living in the house 3 months ago and this valve is leaking into the basement. New tiled bathroom and new kitchen behind it, no idea what to do? The contractor says he's coming over this weekend and praying for a miracle. Do not purchase this valve from Delta Shame for the manufacture of such a product. Edit: After opening the wall, the contractor found a leak. A screw was drilled into the pipe. The problem has nothing to do with this product. This valve works perfectly.
