Wade products are often used within the following sectors: Commercial & Retail – Food, Drink and Kitchen – Healthcare, Education, Leisure and Public Sector – Industrial and Warehousing – Residential.

No – because this standard applies only to grease separators, not to biological type grease converters. There is no standard covering grease converters. On account of this, demonstrating third party approval, in 1989 Wade became the first manufacturer of grease converters to be awarded an Agrément Certificate.
UK building regulations Part H, para 2.2.1, states ‘Drainage serving kitchens in commercial hot food premises should be fitted with a grease separator complying with BS EN 1825 Pt 1, and designed in accordance with BS EN 1825 pt 2 or other effective means of grease removal.’
The underlined (by us) text is intended to permit the use of biological converters which would otherwise be prohibited.

The Water Regulations Guide, published by the Water Regulation Advisory Scheme (WRAS), interprets the regulations and identifies how various systems should be installed.  The Wade Water Point is a WRAS approved product and meets all the requirements of the regulations providing it is installed with a ‘listed’ double check valve or some other no less effective backflow prevention device on the inlet side of the unit, the main purpose of this being to prevent contamination of the water supply.
If the Water Point is to be used to connect to an irrigation system, then it may be necessary to combine the above double check valve with a pipe interrupter with atmospheric vent, dependant on circumstances and downstream fluid category. Consult the Water Regulations and/or the Guide for full details of the various types of installation. The Water Point must also be so installed as to be readily accessible for examination, repair, replacement or operation.

No – Wade roof outlets are designed specifically for gravity fed drainage systems.

Yes, dependant on quantity and particular product Wade offer grade 316. Contact our Technical Services Dept. for further information.

When the outlet is installed vertically gravity assist in draining the outlet, whereas when installed horizontally this reduces the flow rate as gravity is not assisting as much and friction also occurs which slows the rate down.

Yes. All Wade plastic and cast iron gully bodies can be installed in either a timber deck or concrete floor, although for timber decks some of the larger cast iron versions can be quite heavy and, thus, additional support may be required.

Although not necessarily detrimental to the actual function of the converter, the fitting of a waste disposal unit is not advisable because it will necessitate regular cleaning out of the converter.  Note that waste from vegetable peelers must be filtered before discharging through a converter.  Grease Converters are designed to convert waste grease, not food solids, to water soluble products which can be safely flushed through the drain system.

Wade Grease Converters are not designed to cope with cooking oils and, therefore, apart from small volumes associated with washing up residue, any cooking oils should be disposed of separately. We recommend that cooking oils and waste food be prevented from entering the converter wherever possible.

We cannot supply any easy/automatic way of preventing the water seal in a trapped drain assembly from drying out, but would suggest that where a drain is in an infrequently used area, giving rise to the risk, then a periodic check on the water seal is carried out and if necessary topped up manually by pouring water directly into the drain

When the security screw option is selected (suffix ‘H’), the standard pozi-drive screws are replaced with Pin Torx type screws. These screws have a 6 pointed star shaped recess with a small pin in the recess. Pin Torx wrenches are available from most good tool stockists or direct from Wade. Wrench sizes required are dependant on screw size as follows:
For M4 screws – TX20 Pin Torx wrench
For M6 screws – TX30 Pin Torx wrench
For M8 screws – TX40 Pin Torx wrench
Note, any products with a 5mm slot ‘Streamline’ grating will be supplied with Pin Hex screws instead of Pin Torx.

All outlet threads on floor gullies and roof outlets must be sealed with a good quality thread sealant or PTFE tape. Threads on spigots and adaptors must be sealed with a good quality thread sealant.
