Steps To Be Followed Wg Ahile Installin Bath Tub
If you want to install a bat tub in your bathroom then before installing it at desired position, fit the overflow, taps and trap first as it will become difficult to do it once the bath is fitted against the wall. You also need to put some adjustable feet on the bottom on the bath in such a manner that you can raise the rim of the bath at the required height.
If you have separate taps for hot and cold water then you would just fit these as you would do for a washbasin. If you have a mixer tap, you must be supplied with a long sealing gasket. This long sealing gasket slips over both tails by lowering the tails through the holes in the rim.
Place top-hat washers onto them and tighten both of the back-nuts to secure the mixer securely to the bath tub. Get approximately a 22mm flexible copper pipe and fit onto each of the tails.
These flexible pipes will help in easy adjustment that will be helpful if the joints are slightly misaligned. You can also attach short lengths of standard 22mm (3/4inch) copper or plastic pipe with tap connectors.
You can also use a combined waste and overflow unit to your bath tub. In case you will use a flexible plastic hose, this would take water from the overflow outlet to the waste outlet. A flexible pipe of a compression-fitting unit is used to connect to the trap itself but with a banjo unit you could fit the overflow before the trap.
Now spread a layer of silicone sealant under the rim of the waste outlet or fit a circular rubber seal. Before inserting its tail into the hole in the bottom of the bath, seal the thread with PTFE tape.
On the underside you need to add a plastic washer and then tight the large back-nut, bedding the outlet down onto the sealant or the rubber seal. Excess sealant should be wiped off. Then bath trap needs to be connected to the tail of the waste outlet with its own compression nut.
The threaded boss then can be passed over the over-flow hose through the hole located at the foot of the bath. Slip a washer seal over the boss and then using pliers, screw the overflow outlet grille on. In case you are taking help of a compression-fitting overflow then connect the nut located on the other end of the hose to the cleaning eye of the trap.
