As another customer wrote, this faucet is beautiful to look at, but not much else. I also had the pressure problem with the hot water side, but managed to fix it. However, what prompted me to write this review is something else that says more about Price-Pfister's character, more on that below. First though, about the pressure problem, this might be helpful to anyone else having that problem. In my case, there was just a trickle of hot water, although the cold side was fine, so that suggested the problem was in the supply lines somewhere. When I took the hot water supply connection apart, I looked inside of the faucet side connector with a flashlight, and found a tiny piece of black rubber clogging the hole up. Apparently, it had torn off of the little black rubber washer when I tightened it. Strange, even though the connector is rather large, all the water gets funneled into a tiny hole inside it about the size of a pencil lead, if that, so it didn't take much to clog it. Anyway, I went through heck to run water through it backward (somehow), and it did the trick. Flushed it out and it's worked fine ever since.
The real problem that pi**ed me off though was that after about four months, I pulled the spray hose out and I heard something make a loud clunk sound under the sink. When I looked underneath, I found the soap bottle laying there with all the soap spilling out. Apparently, the hose had hooked onto it and when I pulled it out to rinse some dishes, it snapped the plastic tube off that holds the bottle, the same tube that the "sucker straw" goes down through to suck the soap up out of the bottle. Being an engineer, I figured "no problem, my bad" and I looked closely at the tube to see what I needed to do to fix it. Upon close inspection, it was a simple plastic tube that had snapped off (but why wasn't it a metal tube?), the same one mentioned above, that runs through the countertop with a large nut underneath that fastens it in place. The tube is not molded permanently to the soap dispenser's base, but rather it simply screws into the base, so really it's just a simple plastic tube with screw threads on the outside from end to end, but it's also threaded on the inside at one end, which is where the soap bottle screws into it underneath. Interestingly, it snapped off right at the point where the two threads (inside & outside) formed a REALLY thin spot in the plastic, right at the top of the soap bottle. So what I found was the soap bottle still screwed into a small chunk of that plastic tube, but the rest of the tube was still fastened to the countertop. Anyway, it didn't sound like it would be too complicated of a part to look for, so I headed to the store to find a replacement. I was confident that I could find a fix at the store because if they didn't have a direct replacement I could just go to the plumbing section and find a nut (or pipe coupling, which is essentially a small section of pipe with a matching thread on the inside, like a really long nut) that would fit it, and then screw that on right where the tube had snapped off - which would essentially be a way to screw them back together. It wouldn't have to withstand a lot of force, so even if it was a little loose I was sure it would work. However, my experience at the store made me swear I would NEVER buy another Price-Pfister product again. And what I found was simple - NOTHING. By that I mean not only was there no direct replacement, but the plastic tube is a non-standard size, meaning one can NOT buy anything for it, not even a nut to fit it, except from Price-Pfister directly, but even that's complicated. It appears that PF has designed a tube with screw threads different from any standard thread size on the planet. In other words, PF has clearly engaged in trickery and sleazy design tactics to ensure that 1) the soap dispenser is LIKELY to break off because the tube has a very thin WEAK place that is 2) plastic instead of metal, and 3) they can conveniently claim it's the user's fault because one shouldn't pull the hose out I suppose, 4) one can not find a replacement part, except from the manufacturer, 5) the manufacturer will not sell only the tube, but instead will 6) only sell an entire replacement soap dispenser for $69.00 which 7) contains the same flawed tube that will again break under normal use one day.
Now that I know PF's business ethics, I decided I had better take a close look at everything before I have something else send me off the deep end, and I found another potential trap awaiting me. The connection where the spray hose connects to the faucet is also a small thin plastic piece that I believe is also designed to break off with a not-so-hard tug on the spray hose, so now I know I have to find something to prevent that too. I think the best way is to fashion some type of clamp to secure the hose to the inside of the cabinet or wall in order to prevent it from being pulled to the limit of its length - which would certainly snap off the other plastic connector (where it connects to the faucet). Think about it: thin plastic connectors on parts that are INTENDED to be pulled on. That really takes the cake! I also plan to rig some kind of a box or small compartment for the hose to live in when it's pushed down in there (i.e., when it's not in use), so that when it is pulled out, it can NOT get hooked on anything else (like a soap bottle).
It's really sad that one has to modify the installation of a high-dollar product to prevent it from being destroyed under normal use. Sad character statement for Price-Pfister, IMHO. Now that you know what that company is made of, think hard about how precious your money is before you hand it over to them.
