The quality of the product corresponds to the price. Requires little plumbing skills to do it yourself. Be sure to wrap enough Teflon tape around the threads. I also put non-toxic pipe dough over the teflon for a better seal. Did a little soldering, although you may not need it depending on your setup. You can also buy shark bite tools and don't have to solder anything at all. After installing the tested system, a slight drop in pressure of about 8 psi is not very noticeable unless I have multiple sinks running at once. So far in a few days this has got rid of the water smell from my fountain when I showered, still faint but I may have to keep it running for a few more days as I didn't flush the water heater. I also installed a bypass in case the filters get clogged or I need to change them, there might still be water in the house.
