FloPlast has taken the responsibility of CE marking the products in accordance with harmonised European standard BS

EN 12380: 2002 and data is given in FloPlast’s Declaraon of Performance as applicable to the range.

1.0 Technical Specicaon

1.1 AF32/AFE32: The AF32 and AFE32 have been designed for installaon directly onto 32mm UK designated Solvent

Waste Pipe. with the use of the universal adaptor (provided with the product), the AF32 can also to be installed onto

40mm and 50mm UK designated pipe. The valve is also available designated as AFE32, which has been designed for use

with Eurpoean designated 32mm/40mm and 50mm Solvent Waste Pipe.

FloPlast’s AF32 Air Admiance Valve, (as seen on the front cover) comprises of an injecon-moulded, two-part acry-

lonite butadine styrene (ABS) body, screwed together incorporang an EPDM sealing ring. The valve incorporates a slid-

ing ABS injecon moulded disc and EPDM (ethylene propylene diene monomer) seal (poppet), this acts as the opening

and closing seal.

1.2 AV110/AVE100: The AV110 has been designed for installaon directly onto 110mm UK designated pipe. The

AVE100 has been designed for use with European designated 100mm Pipe.

FloPlast’s AVE100/AV110 Air Admiance Valve, (as seen on the front cover) comprises an injecon-moulded, two-part

poly vinyl-chloride (PVC-U) body, screwed together incorporang an EPDM sealing ring. The valve incorporates a sliding

ABS injecon moulded disc and EPDM sealing ring (poppet) which acts as the opening and closing seal.

1.3 AF110: The AF110 has been designed for installaon directly into 110mm UK designated pipe with the use of

and EPDM nned seal. Addionally the AF110 can be installed solvent welded directly onto 82mm UK designated pipe

by removing the nned seal and using the socket on the body. The valve can also be installed directly into 100mm or

110mm European designated pipe with the use of an EPDM nned seal, this product is designated AFE110.

FloPlast’s AF110 Air Admiance Valve, (as seen on the front cover) comprises of an injecon-moulded, two-part poly

vinyl-chloride (PVC-U) body, screwed together incorporang an EPDM sealing ring. The valve incorporates a sliding ABS

injecon moulded disc and EPDM seal (poppet) which acts as the opening and closing seal.

1.4 AX110: The AX110 incorporates the same features as the AF110, with the excepon of the inclusion of an insect/

debris grill manufactured from Polypropylene.

Document H of the Building Regulaons Clause 1.33 states that AAV’s should not be used externally or in dust laden at-

mospheres, however due to the design criteria requirements of the terminaon of SVP’s within 3 metres of an opening

window, and the use of the roof as habital space and also the upturn in lo/roof area conversions, and as a means of

overcoming unsightly SVP installaons, Building Control Ocers are accepng their use.

FloPlast strongly advise that conrmaon of acceptance of the use of the AX110 is gained from Building Control prior to

installaon.

1.5 These valves incorporate spigots detailed in Table 1. They incorporate a nned seal for installaon into 110mm and

100mm pipes or ABS and PVC-U solvent sockets.

1.6 The valves incorporate spigots with diameters that are in accordance with the standards for waste pipe, including:

BS EN 1329-1, BS EN 1455-1, BS EN 1565-1, BS EN 1566-1, BS4514 and BS5255.

1.7 Connuous quality control is exercised during the manufacture and assembly , including visual checks, checks on

dimensional accuracy and 100% funconal tesng of each product. The raw materials and bought-in goods are subject

to quality controls as dened within our ISO9001 Quality Mangement System (FM 501414).

1.8 FloPlast AAV’s are designated A1 in accordance with BS EN 12380: 2002 and can be ed below the ood level of

connected appliances, in air temperatures between -20°C and 60°C.

2.0 Manufacture

2.1 The materials used to manufacture the piece parts in FloPlasts AAV’s are dened in secon 1 above and in the main

use convenonal injecon moulding techniques. The EPDM poppet seal and the ‘O’ rings used to seal the lids are pur-

chased from rubber manufacturing specialists and are assembled on the poppets and bodies respecvely.

2.2 As a part of the assessment and ongoning surveillance of product quality under FloPlast’s Kitemark accrediaon

(KM51247), BSI has:

• Agreed with FloPlast the quality control procedures and product tesng to be undertaken.

• Assessed and agreed the quality control operated over batches of incoming materials.

• Monitored the producon process and veried that it is in accoirdance with the documented process.

• Evaluated the process for manufacturing non-conformies.

• Checked that all equipment has been properly tested and calibrated.

Undertaken to carry out the above measures as a part of the surveillance process to verify that the specicaons and

quality control being operated by FloPlast are being maintained.

2.3 The management systems of FloPlast have been assessed and cered as meeng the requirements of BS EN ISO

9001: 2015 by Brish Standards Instute (Cercate KF501414).

3.0 Delivery and site handling

3.1 FloPlast AAV’s, complete with their adaptors, (where applicable), along with installaon instrucons are supplied in

cardboard boxes and polyethylene bags, to limit the risk of contaminaon or damage. All valves must be stored upright

in their boxes unl required for use.

3.2 The legend of the distributor is incorporated in to the lid of the product and is shown on the packaging. In addion,

all FloPlast valves have CE mark designaon A1 to BS EN 12380: 2002, the details of which appear on the boxes.

4.0 Design Consideraon - General

4.1 The FloPlast Air Admiance Valves when used in above-ground drainage systems designed with BS

12056-1: 2000 and BS 12056-2: 2000, the valves are sasfactory for use to:

•admit air under condions of reduced pressure in the discharge pipes and prevent water seals in traps

from being drawn or evacuated

•prevent the release of foul air from the drainage system, and

•contribute to the venlaon of the main drain to which the discharge stack incorporang the valve is

connected

4.2 The 32mm and 40mm valves are designed for connecon to waste pipes to prevent water loss from trap seals by

self and induced siphonage arising from water ow in small diameter branch discharge pipes.

4.3 The 50mm valve is for use on branch discharge pipes.

4.4 The 82mm, 100mm and 110mm valves are desigined for use on discharge stacks up to 45 metres or 10 storeys high.

4.5 The FloPlast valves are designed for use in associaon with each other or separately.

5.0 Praccability of installaon

FloPlasts AAV’s are designed to be installed by a competent general builder, or a contractor experienced in these types

of products.

6.0 Drainage System Design

6.1 Drainage systems designed in accordance with BS EN 12056-1: 2000 and BS EN 12056-2:2000 should

be based on the airow data given in Table 2. Typical installaon details in accordance with BS EN 12056-

1: 2000 are given in Figures 3 and 4.

6.2 To contribute to the venlaon of the underground drain and to minimise the eects of excessive back pressures

when a drain blockage occurs, the branch or main drain serving a stack or stacks ed with a FloPlast valve may require

a venng point upstream of the stack connecon. Guidance is given in Table 3 and Figure 5.

charge stack) to be provided at the vent stack at

the head of the installaon and at mid-point of the

system.

Figure 5 Examples of drain venlaon provisions

6.3 To prevent self-siphonage a connecon to the AF32 or AFE32 valve is required within 1500mm of the trap (see

Figure 4).

6.4 To prevent induced siphonage in a row of wash-basins, a AF32 or AFE32 valve can be ed between

the two wash-basins furthest from the discharge stack (see Figure 4).

6.5 Air admiance valves should not be used as the only venlaon to sepc tanks or cesspools.

6.6 The valve should be installed within the building where it is easily accessible but not subject to inter-

ference from vandals.

6.7 If the valve is to be installed in, or in close proximity to, an habitable space where noise of operaon may cause a

nusiance, then consideraon must be given to the use of a suitable form of sound insulaon.

6.8 In addion, other than those shown in Figure 5, stacks should not be ed with the valves when the connecng

drain(s) are subject to periodic surcharging or are ed with intercepng traps. An open-topped discharge stack or

venlang stack should be used in such cases.

7.0 Eect on water seals

7.1 The valves will admit sucient quanes of air into the stack when they are subjected to a reduced

pressure and there by prevent loss of the water seals in appliance traps.

7.2 Under condions of increased pressure in the drainage system, each valve will remain closed, thereby prevenng

the release of foul air into the building.

7.3 A pressure increase sucient to raise the level in the water seal or to cause foul air to bubble up through the seal is

an indicaon that a drain blockage has occured or that the system is being overloaded or otherwise misused.

8.0 Maintenance

8.1 FloPlast valves do not normally require maintenance.

8.2 In the event of accidental damage or vandalism the valves must be renewed.

9.0 Durability

FloPlast valves are manufactured from materials convenonal in drainage systems. Repeated opening

and closing will not adversely aect the sealing or operaon of the valve. When used in the context of

this data sheet the valves will not be subject to signicant deterioraon and will have a life equivalent to

that of the drainage system in which it is installed.

10.0 Re-use and recyclability

The product contain PVCu, ABS, EPDM rubber and synthec rubber, which can be recycled.

11.0 Installaon

11.1 Installaon must be carried out in accordance with these instrucons.

11.2 FloPlast AF110 & AX110 valves are supplied with a synthec rubber connector enabling a push-t into 100mm and

110mm as indicated in Table 1. Addionally if the rubber connector is removed from the valve a solvent cement socket

will be revealed enabling connecon to 82mm pipes as indicated in Table 1.

11.3 FloPlast AVE100 and AV110 are supplied with solvent cement sockets enabling a solvent cement connecon to

pipes AS INDICATED IN Table 1.

11.4 FloPlast AF32 & AFE32 valves are available in both UK and European designated sizes, supplied with a solvent weld

socket on the main body for 32mm with an adaptor enabling the product to be connected to solvent welded pipe as

indicated in Table 1.

11.5 FloPlast AVE100, AV110, AF110 and AX110 valves must be ed in a vercal posion 200 mm above the highest

branch connecon (see Figure 3). As FloPlast valves are A1 designated to BS EN 12380-1: 2002 it is possible to locate

them below the lowest reservoir being vented.

11.6 FloPlast AF32 and AFE32 valves must be ed in a vercal posion at least 100mm above the pipe being vented.

As FloPlast valves are A1 designated to BS EN 12380-1: 2002 it is possible to locate them below the lowest reservoir

being vented.

11.7 The valves are easily installed in discharge and/or venlaon pipes and eliminate the need to penetrate the roof

covering. Care should be taken to avoid contaminaon of the sealing surfaces, as this may aect airghtness.

12.0 Technical Invesgaon – Tests

12.1 Tests were carried out and the results assessed against BS EN 12380: 2002 to deternine:

• impact resistance (drop test)

• airghtness aer endurance at negave temperature

• airghtness before and aer endurance at posive temperature

• opening pressure

• airow capacity

13.0 Technical Invesgaon

13.1 The manufacturing process applied to these products are controlled with FloPlast BS EN ISO 9001: 2015 Quality

Management System (Cercate No. FM501414). These processes are regularly audited by representaves of BSI to

ensure connued compliance with our detailed processes.

13.2 FloPlast’s valves are subject to type tesng and audit test as deterrmine with the Kitemark scheme to which they

are cered, (Cercate KM512474). Tesng is undertaken on behalf of BSI at the Building Research Establishment also

known as BRE.
