I was listening to the Ubell's & there were 2 items that caught my attention, so I tried to find larryubell.com - site, but it says it doesn't exist. What gives? There isn't a link on the Lopate show, how come?

Oh darn--ratchet. Great show!

My bathtub (enamel) got damaged during a renovation - chip the size of a dime.
Any ideas on how to fix it?

Your quiz--the answer is the LEVER.

I love your show, and I remember one when you advise a listener about air purifier.
 I am looking for an efficient air purifier for an approx. 800 SQ. FT. I looked around and I found those that require a regularly filter replacement which makes them significantly costly. I remember seeing an TV commercial, advertising one with washable filter (a while ago I remember a TV commercial which was advertising one with washable filter).
 Would you recommend any  without filter replacement ?
I prefer a HEPA but it doesn't have to be because the purpose is to keep the air and area free of dust
 Please advise. Thank you

My wife wants new tiles in the bathroom -- is it practical to put new tile over the existing tiles?

Hi guys! Gotta a little baby who Has just now started to sleep in his own room
On the second floor of our 1958 Cape here in northern NJ. We have vents on the second floor bringing forced air in, but no returns? I'm thinking our little guy is going get pretty hot this summer. But my husband thinks he'll be okay with the AC on. Our bedroom is downstairs so we won't be on the same floor, but we want to make it as comfortable as possible for him. Need to put in the vents?

I need to turn on the water in my house elsewhere. The water was turned off by a plumber so that it would not freeze in the pipes. Please go through the procedure for turning on the water. The plumber is not available for when I need the water to be turned on.
