This toilet bidet sprayer kit is designed with user needs in mind, featuring a 7/8 in. T-valve (approx. 22.05mm diameter) that fits most American toilets, effectively preventing wrong purchases due to size mismatches. It supports 2-installation methods: tank mount and wall mount. The tank-mounted installation is simple—just hook the sprayer holder onto the toilet tank without drilling, saving bathroom space. Wall-mounted installation offers flexibility for diverse needs, serving as a multi-functional sprayer for cloth diaper cleaning, pet bathing, car washing, baby showers, and more. Operation is effortless: press the spray lever to adjust water pressure, and fully depress it for a powerful jet stream that stops automatically when released. The design prioritizes leak prevention with a nylon T-valve for precise fit, a cone washer for secure sealing, and a brass valve for zero leakage, ensuring peace of mind during use. Crafted from 304 stainless steel, the kit boasts exceptional durability, oxidation resistance, and corrosion resistance, effortlessly handling daily toilet cleaning and various other scenarios to deliver a fresh, comfortable experience.
