Janieful: "The advanced toilet makes sense to me - at least much more than a separate bidet would. I have never used either, but bidets take up so much space. The one in all model is much more practical." The advanced toilet seats are not, strictly speaking, direct replacements for bidets, though one generic term for advanced toilet seats is "bidet seat." The first and foremost function of an advanced toilet seat is water washing a bit further to the rear than a bidet cleanses. Cleansing the anus with water is far superior to wiping (and spreading) with dry paper. Most current models of advanced toilet seat have a second washing function called "feminine cleaning," or a variant thereof, which has many similarities to the function of a bidet. As you may guess, that function directs the water somewhat further forward than the primary function does. However, in "real" bidets, the water comes from the front, whereas in advanced toilet seats, the water approaches from the rear, so there is a difference. The various brands of advanced toilet seats approach these functions in different manners. Inax, which invented the advanced toilet seat category, determined that the optimal angle of incidence of the spray on the anus should be 70 degrees from horizontal or, in other words, just 20 degrees from vertical. The Inax advanced toilet seats therefore have spray wands for posterior cleansing that extend out fairly far, so that the spray can be more nearly vertical. Toto, the biggest player in the market, was obsessed by the spectre of "backwash," the (small proportion of the) water that rebounds off the user's posterior, and accordingly Toto Washlets are designed to spray water at the anus at 43 degrees from horizontal, which reduces (but does not not eliminate) the amount of backwash that hits the spray wand. But spray directed at Toto's 43 degree angle does not wash as effectively as the 70 degree spray of the Inax models does. Inax addresses the backwash matter with an aggressive self-cleaning cycle for the spray wands, executed both before and after each use. As to the feminine function, Toto can get by with a single wand for both posterior and feminine cleansing, with two spray nozzles in the single wand, because the 43 degree spray angle for the posterior wash already is so shallow. Inax has to use a separate dedicated spray wand for feminine cleansing, because the wand that Inax uses for posterior cleansing would not be positioned well for the feminine cleansing function. But, whether or not you use the toilet seat for bidet-like functions, water-assisted posterior cleansing is a huge step up from dry wiping after a bowel movement. There probably is no way to upgrade your bathroom more effectively than to replace a passive toilet seat with an advanced toilet seat.

@davidro1, I'm not concerned with the pop-up mechanism at all. I was concerned with the pop up housing being level with the drain line. I was worried that if water stayed in the pop up housing, that the housing might be prone to leaks (at the point where the ball and rod go into the drain pipe). I was also concerned with any code issues. I remember reading somewhere that there is a maximum allowable distance the p-trap can rise from the low point to the drain line. I assumed that reversing the j-bend would result in too much of a height difference to be code compliant (I'm still assuming this, since nobody has chimed in on this issue). However, more than the legality of it all, I really just wanted to know what bad consequences might happen as a result of reversing a j-bend. @jimsonburg, Thanks for the SPAM. Not. @homebound, I was concerned about the connections. The waste arm has the flared tip, but it doesn't seem so different from the plastic washer thing that goes in the tailpiece. I've went ahead and reversed the j-trap, and everything fits fine and feels really solid. I filled up the sink, drained it all at once, and there are no leaks. I've even opened up the pop up housing (where the ball goes in) and to my surprise, there is no standing water in there (the water line sits just below that). I'll keep an eye on it to make sure nothing leaks. If it does, I'm sure we'll notice it right away, before there's any major damage. Aside from a few bottles of cleaning supplies, we don't really use the cabinet under the sink, so maybe I'll just leave an old aluminum lasagna pan down there. At least that way, it'll catch any leakage should any occur, and it will alert me to any leakage by amplifying the sound of any drips.

The little sink plunger is called the pop up. I haven't seen the ones that aren't connected. That sounds like a newer system -- no idea. Danze and Brizo are fairly high end brands though Brizo is fancy Delta I believe. It's most helpful for suggestions if someone posts photos. Vanities are generally 36" high. So, if the med cabinet is a tall one, it needs to clear 36 plus the height of the faucet, plus say 2 inches. With a 48" vanity and a single sink, I wouldn't want a tiny faucet. If you get a modern style with a top lever that ads to the height. A bridge faucet or separate hot/cold spouts should be lower. I'm planning a budget powder room expansion to add a shower to our first floor. I made sure I went to the showroom and handled the shower fixtures. I would do the same with sink faucets. The heavier the better (more brass). There aren't so many complaints about bath faucets. Most have ceramic cartridges which can break but are easy to replace. Warrantys vary so I'd read the fine print. Also, some manufacturers, like Rohl, have tiers of product. I happen to have Rohl/Perrin & Rowe nickel faucets & shower in our master. Those have been excellent and 0 issues in 12 years. They still look new. I love the color of the nickel but would likely not get it again as it needs to be polished up periodically.

We tried closing the valves, doesn’t help much only if the pressure is really low and water goes directly down to the drain hole. I also read the reviews for this faucet (which I should have done before purchasing:) and many people are experiencing the same issue. I called Brizo today they offered to send me some replacement parts but the faucet is barely new not like I need to fix something. I also saw on their specs papers tgere is an aerator that controls the flow , the only thing I don’t understand if this surstor attached in the bottom of the faucet or it’s something inserted inside. The 2 parts I circled on the picture is what they are sending me, not sure if it will help.
