I just installed a new SMART bidet in my master bathroom but I can’t find the right fitting to connect the supply line. I need 3/4 male NPT to 3/8 female NPT. I’ve made many trips to Home Depot and even order from Amazon. The 3/4 male end fits but the 3/8 female end doesn’t fit the water supply value in the wall. I tried 1/4, 1/8 to no avail. I need a price quote.
