I have some leftover Ditra from an earlier tile job. I am doing an entryway with a floating floor and was wondering if the Ditra could be used as an underlayment/height riser under this type of flooring. It raises the floor perfectly to the height of the existing solid hardwood floor. Searched...

Before I regret a wrong choice... Just purchased an ABS tub surround and contrary to their directions, which call for drywall to be used in the tub/shower area, I have used Durock cement board. My own preference is to NOT use any drywall in this area and the CBU is already up and not going...

Finally have my water heater tank ready to go. The proper method to use the water heater from what I've read is to first let the tank fill and open a faucet for the hot water. When the faucet flows the tank is filled and power can then be applied to the tank. But if a thermostatic mixing valve...

Just replaced 1965 era DW supply from meter from 1/2 to 3/4 copper and added in a PRV. Now working on main HW line. Two questions I have. First, I am adding a 40 gal HW heater tank being fed from existing boiler HW line. Boiler has expansion tank on cold water feed already. Do I need to add...
