How to Upgrade to a Pressure Balanced Shower Valve

Richard travels to Salt Lake City to replace a shower valve he has never seen before in his career with a conventional pressure balanced one.

Where to find it?

Richard installed a Temptrol Pressure Balanced Tub/Shower Valve, which is manufactured by Symmons. They also manufacture the retrofit cover plate Richard used to conceal the hole left behind from the old valve.

The sink hole cover the Richard used to seal the hole from the old shower head is manufactured by Danco and can be found at home centers.

The other materials Richard used to complete the valve replacement, including the copper pipes, copper fittings, solder and flux can all be found at home centers and plumbing supply houses.


How to Refinish Worn Out Stair Treads

Nathan demonstrates how to refinish stair treads.

Where to find it?

To refinish stair treads, the old finish will need to be completely sanded off. To do this, Nathan used a variety of tools, including a Rotex 150 multi-mode sander for the majority of the tread, a scraper for the corner of the stairs, and a Sanding Mouse Hook and Loop Sanding Block for around the balusters and the nosing of the tread. The sanding block can be found online.

To remove the dust, Nathan used a HEPA Dust Extractor with a brush attachment by Festool and a tack cloth, which can be found at home centers.

To apply a new finish, Nathan used a regular paintbrush and a water based polyurethane by Rust-Oleum.


How to Clean and Prevent a Mossy Roof

Tom helps a homeowner remove moss from his roof and prevent it from growing back.

Where to find it?

When working on a roof, safety is very important. Tom added a roof anchor to the rafters, wore a harness, and used a safety line. These can be purchased at home centers or hardware stores.

Tom used a push broom to gently remove the loose pieces of moss.

He then installed a roll of zinc strip moss preventer, which can be purchased online or at specialty retailers.

Finally, he sprayed down the roof using a solution of water and bleach. He started at the bottom of the roof and worked up so that he wouldn’t step on wet areas and slip.
