Review on H.E Home Bidet Sprayer for Toilet: Easy Install, Leak Proof Hose, Complete Jet Spray Kit, High Pressure Toilet Sprayer - Perfect for Cloth Diapers! by Michael Gutierrez

The internal problem with these metal bidets is their hard and sharp threads. They will not thread onto the soft plastic threads found on most toilet float valve stems. They will cut their own threads and screw in crookedly, resulting in a poor seal and leakage. It's stupid of them to include teflon tape as it's not needed for compression joints. Keep in mind that you may need to replace the float valve with a brass screw base valve. They fit perfectly with the metal body of the bidet and ensure a good seal. Be warned, I have about 7 of these installed. They cut their own strings and you often have to replace your toilet's float valve. If so, buy with a brass shank, not plastic. A few euros more but worth it.
