1 Whenever you choose European (or English) seat for your bathroom, besides checking the Make, ISI mark, colour and First Quality mark, see that the height of closet above floor is minimum 390 mm. Also see that the depth of water seal in it is not less than 50 mm. Water seal is depth of water above the top point of outlet. Don’t go for commercial quality seats. Though these are cheaper by 10 to 15%, their glazing fades vary soon. Ensure that the WC is free of cracks and in one piece with at least 2 or more holes of 6.5 to 7 mm diameter at its base for fixing it to the floor. Ensure to add washers to the bolts. Further see that the joint of seat with the floor is sealed well.
2 A WC needs a P trap or S trap for its connection to the soil pipe. P trap or S trap may be separately supplied or can be an integral part of the seat. The P trap has an angle of 140 to the horizontal while the S trap is at right angle to horizontal. Provide a P trap if the soil pipe to which the seat is to be connected is running inside the wall. Provide an S trap if the pipe for disposal is through the floor. Mostly soil pipes run inside the walls, therefore P traps are required. For first floor and above, only P traps will be required. Only in exceptional circumstances and that too at ground floor only, disposal pipe may be running through the floor and an S trap may be required. There remain more chances of blockage in S trap seats.
3 Prefer seats with P trap or S trap as integral part of them. When the trap is not an integral part of the pan, fix its joint with the pan in 1:1 cement mortar.
4 For European seats, choose seasoned teak wood lids. Otherwise solid plastic lids of reputed make like Parryware, Commander, Duralite or Admiral may be chosen. Jet spray seat cover is another choice in European seats. Also see that the lid is fixed to the seat by using Chromium Plated brass hinges and screws. Always provide rubber buffers to the lids for their longer life.
5 While choosing Indian WCs, check their Make, first quality and IS2556 mark. All colours are available these days to have a colour combination with chosen tiles. Check that the pans have sufficient slope and not less than 150 to the horizontal towards the outlet for easy and quick flushing. Foot rests must be of minimum 10”X5”X1/2” size to provide full bearing to the feet. When the foot rests are not separate but an integral part of the seat itself, the WC is called Orissa pan. Foot rests may be flush with the top of WC or raised ones as per requirement of the user. Indian seats are also called squatting pans. For Indian WCs also, P or S traps may be supplied separately or may be an integral part of seat as in case of English seats. Prefer seats with integrated traps. See that the water seal of the traps is minimum 50 mm. If a P trap is used, it must have a downward angle of 140 to the horizontal. If separate traps are chosen, see that the traps too are IS 2556 marked. That should ensure the water seal and inclination requirements. Note that even for integrated seats, S trap may be in 2 parts, one part integrated with the seat and second part in shape of a bend to be jointed at site.
6 While fixing Indian seat pan in position, always take care that the space between the pan and the concrete base provided below it is fully filled with concrete and no hollow space is left there. Otherwise the pan will develop cracks very soon.
7 Besides English seats and Indian seats, another type of seats available in the market are Universal seats. These seats combine the benefits of both the Indian as well as English seats and are called Anglo Indian seats also. These seats are raised ones like English seats and also have foot rests integrated with them for squatting over them like Indian seats. Choose these seats if you want to however using these as English seat is sometimes uncomfortable for people because of the integrated foot rests. Height of these seats above floor level is 380 mm, just 10 mm less than that for English seats. Look for IS 2556 mark for these seats.
Happy building!
