Original Air Date: Week of October 18, 2007

Plumbing and heating expert Richard Trethewey helps a homeowner replace a broken cast-iron "closet flange" for a toilet. Then Richard, along with landscaping contractor Roger Cook, general contractor Tom Silva and host Kevin O'Connor ask, "What is it?" Afterward, Tom helps a homeowner repair a cracked plaster wall using a new type of adhesive system. Back in the loft, Roger shares a tip on digging holes sent in by a viewer.

How to Replace a Toilet Flange

Richard helped a homeowner with a wobbly toilet. With the toilet removed, he determined that it rocked back and forth because the cast-iron toilet flange sat up too high. The homeowner had recently replaced the tile floor and the finished height of the new floor was slightly lower, causing the closet flange to sit up too high. Richard decided to carefully break off the old flange using a mallet and cold chisel. He then replaced the old flange with a new one that attaches to the “closet bend” using a compression fitting. Richard secured the new flange to the closet bend by tightening four bolts with a socket wrench and reinstalled the toilet.

How to Repair Cracked Plaster

Tom helped a homeowner repair an old, cracked plaster wall using a new system for securing the plaster back to the wooden lath underneath. Tom started by drilling a series of holes in the plaster and then vacuumed out the loose debris. He then sprayed a “conditioner” and injected a special adhesive into each hole. Tom then used plastic washers and screws around the cracks, which acted like “clamps,” pulling the sagging plaster back tight against the wood laths. Once the adhesive had set, Tom removed the plastic washers and applied joint compound over the entire area to fill the holes and smooth out the plaster.

Viewer Tip

Roger shared a tip from a viewer that described an easy way to measure the depth of a hole while using a “clam shell” type post- hole digger: Simply mark the length of the handle of the digger to measure the depth of the hole easily. Post-hole diggers are available at home centers and landscape supply houses
