With the water off, place your bucket or towel directly under the connection point where the flexible water supply hose meets the bottom of the toilet tank. Using an adjustable wrench or channel-lock pliers, grip the coupling nut on the supply hose and turn it counter-clockwise to loosen and disconnect it from the tank's fill valve. A small amount of water will drain from the hose and tank, so be prepared.

This guide provides comprehensive, step-by-step instructions for installing a modern electric bidet toilet seat. The process involves shutting off the water supply, removing the existing toilet seat, mounting the new bidet seat and its hardware, connecting the water supply via a T-valve, and finally, powering on the unit and checking for leaks.
Frequently Asked Questions
What's the best way to grip a stubborn fill valve nut with channel lock pliers?
Ensure the plier jaws are fully open and square around the nut. Apply firm, steady counter-clockwise pressure. If the nut is very tight, try small, forceful turns rather than one continuous pull to break it loose.
Is there a risk of cracking the toilet tank while removing the nut?
Yes, excessive force or twisting can damage the tank. Apply firm but controlled pressure, supporting the fill valve from the top if possible to reduce rotational stress on the ceramic.
What should I do if the fill valve nut is stuck or heavily rusted?
Apply a penetrating oil, such as WD-40, to the nut and let it soak for 15-30 minutes. If it's still stuck, you may need to carefully cut the plastic nut with a small hacksaw blade or Dremel, exercising extreme caution not to damage the toilet tank.
My channel lock pliers keep slipping, or I don't have enough leverage under the tank. Any advice?
Make sure your pliers are correctly sized and fully engaged with the nut. If space is limited, try repositioning yourself for a better angle or consider using an adjustable wrench if it offers a more secure grip in the confined area.
