Is the leak in a horizontal line? If so, he probably he cannot get it to seal because of residual water. Standard advice is to put a piece of soft white bread in the line. The idea is that the bread keeps water away from the joint, allowing a good seal. Afterwards, the bread can dissolve to not cause any problems from being in the line. I have what I think is a better (but closely related) approach. I spoon a bunch of flour into the line. I then shove a pile of it an inch or so up the line with a dowel close to the same diameter of the pipe. The flour has the same effect as the bread, but it does not have to "dissolve," as it is already a fine powder.

Hot, yes! It's 10 pm, and still 80 degrees. Humid, even more. Central air on plus my box fan blowing across my side of the bed. DH will have the quilt on, and will hate the fan, but he's learned to deal with it, LOL.

10:18 PM, 93 degrees... and another record high today, with 108! Yeah, we keep setting records, LOL Moni

10:30pm here and still 94*! Took DGS to the movies this afternoon and my car thermometer read 119* when we got out. It then cooled down to 107*. Triple digits are forecast for the next 5 days. We live in southwest corner of Utah, just 2hours from Las Vegas. Kids started school 2 weeks ago and school busses are not air conditioned, HOT! HOT! HOT!!
