Master shower leaks

Our new (to us 2 years ago) house came with a large (maybe 36 square feet of floor) tiled shower in the master bath. The inspector warned me that it leaked but I hoped it was simply a problem with the plumbing. I tested the shower pan by sealing the drain and filling the pan with water drawn from elsewhere in the house. It leaked! Water ran under the house. The right thing to do would be to tear it out and replace it but that will be a major undertaking. I wondered if there was something I could do that would delay this major bill? How about coating the floor and bottom rows of tile up to the bench with Epoxy Waterproofer? We decided to try it.

Pipe Diameters

Oddly, there is nothing about a ½” pipe that is ½”, be it copper, iron, or PVC. Nice tables with the internal and external dimensions of pipe of various materials.

Beam size

Kelly’s engineer estimates beam thickness as 1/2 inch per foot of span.

Quarter Master faucet leak

It appears to have a defective washer. Not an ordinary O-ring unfortunately but rather a gasket with a “frill” on it. Their customer service number is 800-782-2385. I think it is a 104-557HC. I called on 7 January and they are sending and entire “stem” rather than just the O-ring. On 12 January I received a new complete “stem” for my faucet. Great customer service. I would have been happy with just the gasket but this will get it working again. B&K Mueller is a quality company. I’ll buy and recommend their stuff for sure.

On further examination I found that the tubular shaft was cracked allowing water to enter it and spray out the knob. I soldered the cracks and it seems to work now.

Air filters

Replaced 1 April, 9 December

Says “lasts up to 90 days”. What does that mean? The upstairs unit runs an average of 3 hours per day. So replace at 270 hours? The downstairs unit runs 2.3 hours per day, so replace it sooner? That makes no sense.

I’ll check them once per month.

Septic

Pumped 21 October 2006 by J.C. Johnson Septic Service. He says it looks good. Suggested adding copper sulfate to discourage the tree roots. This web page at the University of Georgia supports adding copper sulfate and suggests 2 pounds per 300 gallons no more than 2 times per year. He says maple trees are the worst.

Plan to pump again in 2009.
