I have 1/2" inch lines coming into a two person shower. We are going with a 1/2" Grohtherm valve that will feed a Grohe Movario hand-held shower head and a Brasstech overhead rainshower. A Movario fixed head will be on a separate pressure-balance valve. I was told that a 1/2 valve will support two heads but probably not three. Since my husband wants to be able to control his water temp anyway, we went this route. I discussed this arrangement with several people, including a Grohe rep, who seemed to think it will work. We have the rough plumbing done but are in the middle of tile work so I can't say for sure what it is like. Good Luck!

If his pump is only inch and a half, it will NOT. Beyond 75 gpm, head loss increases substantially due to friction and restriction. If the pump uses 2", then plumbing the skimmer and drain to a 3 way valve that accommodates both sizes will help to improve flow. If it's a liner pool that has 1.5" returns, I like to remove the directional eyeballs as they can restrict flow and reduce efficiency also. This may not be suitable for some pools equipped with Paramount's wall cleaning returns since they need be directed along the water line to keep it clean but that is t stated as existing on this pool.

I'd talk to some insulation installers. If they can blow it into the walls, it would most likely help, however it may be very expensive. I don't think the fan would compound the problem. If blowing in the insulation doesn't work, then one would have to remove the sheetrock and apply insulation to the bare stud walls. However, the fact that the home was built in 1976 could be problematic. If the original builder used vermiculite insulation in the walls (not super common, but not impossible) it is laced with asbestos. They may have also used cellulose, which over time tends to clump and sag to the floor. BTW, you might even be surprised to find out your walls have ZERO insulation in them. Until 1977 and the oil embargo, it wasn't unheard of to have uninsulated homes, as the cost of heat was cheaper than the expense of insulation. So, call a couple of insulation firms in to tell you what you have, and more importantly what can be done to rectify the problem. As I said, it's probably not going to be cheap.

Me too! I may not use a ton -- but when I want pumice, it's ALWAYS General Pumice Products I order from. Over the years, I have found the product CONSISTENT in size, low in dust. I no longer sift it, I just wash it and it's fine. I like perlite because it's light in weight -- BUT, living in FL, the humidity turns it a disgusting mustard color AND then it softens in the pot and breaks down, thereby defeating the purpose of porosity. I use pumice WITH SOIL, or with a gritty mix of Turface and Manna Pro....and I use pumice ALONE.
