Materials:Pipes and fittings are manufactured from Unplasticized polyvinyl chloride(PVC-U); Gullies from PVC-U, polypropylene (PP), or polyethylene (PE);Inspection chambers from polypropylene. Couplings can be made from eitherPVC-U or PP and contain a rubber sealing ring manufactured from styrenebutadiene rubber (SBR).

Colour:Pipes, Gullies and fittings are in terracotta. Inspection Chambers and

elastomeric joint rings in black.Standards:The PlastiDrain system is manufactured to the highest possible standards andwhere relevant is manufactured in accordance with BS 4660: 2000 andBS EN 1401-1: 1998 which specifies the requirements for underground pipesand fittings in sizes 110mm and160mm. Rubber seals are manufactured toBS EN 681: 1996.In addition the PlastiDrain system has been independently assessed by theBritish Board of Agrment and has been awarded an Agrment CertificateNo 86/1648.

Quality Assurance:All Hepworth products are manufactured under aquality management system which is approved to BSEN ISO 9001:2000 Quality Management Systems -Requirements.

Maintenance:A PlastiDrain system when correctly designed and installed should not needmaintenance. However, blockages do occur from time to time and the pipeline

will need to be cleared. Provision of access points into the system should bemade in the design of the drainage layout. Should a blockage occur, flexible orroller type rods should be used.

From July 1998 the new Europe-wide manufacturing standardBS EN 1401-1:1998 started to replace BS 4660. However, 110mm and 160mmaccess fittings are not covered by the new standard and will conform toBS 4660:2000.

System Performance

The following notes are given as a broad indication of the main installationmeasures to be considered. Further advice and information can be obtainedfrom Hepworth Technical Advisory Service on Tel: 0870 443 5551.

Trench Preparation:The trench should not be excavated too far in advance of pipe laying andshould be backfilled as soon as possible. Trench widths should be as narrow aspracticable but not less than the pipe OD plus 300mm to enable propercompaction of sidefill. Trench sides should be correctly supported.

The type of bedding and filling needed depends on:-

the pipe type and size

type of subsoil

the load on the surface of the trench (eg. under a road, field or garden)

the depth of pipe under the surfacewidth of trench

These are recommendations made by Hepworth. Standard beddings aredefined in BS 5955: Part 6: 1980 and BS EN1295.

Trench Backfilling:Hand tamp the backfill fully at the sides of the pipe while tamping lightly overthe crown. This should continue until a minimum thickness of 300mm has beenplaced over the pipe. As dug material may then be placed in 300mm layers andmechanically compacted. Dumpers and other vehicles should not be drivenalong the trench as a means of compaction.

Recommended Bedding Requirements

Pipes laid at depths greater than 900mm cover in roads, 600mm in fields. Pipes laid at depths less than900mm cover in roads, 600mmin fields.

t is important that good care is taken on site to prevent unnecessarywastage of materials and time and for the prevention of problemsafter laying thus causing delay and additional expense.

1 Transport:- Generally pipes are delivered pre-packed in standard quantities, held by

nylon straps and timber supports.

Loose pipes are hand loaded, care should be taken to clear the carryingsurface of debris and nails.

Pipes should not overhang the vehicle by more than 1m. Vehicles should

have side supports no more than 2m spacing. With mixed loads of pipes ensure that the larger diameter pipes are at the

bottom.

Fittings are supplied in cardboard boxes or plastic bags.

2 Handling:- Pipes should never be thrown from lorries, dropped or dragged along the

ground. Use web or rope slings when mechanically lifting pipes, do not use metal

slings, hooks or chains.

Take extra care in wintry conditions as cold weather reduces the impactstrength of PVC-U.

3 Storage:- Pipes should be laid on a flat surface free from large stones and projections.

If this is not possible pipes should be placed on transverse bearers with sidesupports.

Stack pipes of different sizes separately, if this is not possible stack largerpipes at the base (see diagram a)

Pipes should not be nested for long periods and stacks should not exceedseven layers or 2m in height.

Sitework and Installation Instructions

4 Cutting:-

To cut a pipe to a specified length, use the following procedure.

a) Mark the pipe, and cut cleanly at a right angle to the pipes horizontal axisusing a fine tooth saw.

b) The cut end should be chamfered to approx 15 for half the pipe wallthickness and deburred with a sharp tool.

5 Jointing:-

Pipes and fittings are joined by push-fit joints. Socket ends are fitted with anelastomeric seal which is compressed by the spigot end of the joining pipe toform an effective seal.

a) Ensure both pipe end and sealing ring are clean.

b) Lubricate both pipe end and sealing ring.c) Align components and push home fully.

If expansion is required the spigot may be withdrawn by 12mm. An allowancefor expansion only needs to be made when using PVC-U couplings. This is notnecessary with the use of polypropylene couplings.

If extra leverage is required to push home the spigot, use a timber block at thetrailing end to prevent damage.

The push-fit joint allows for some angular deflection giving ease of installationwhilst allowing for subsequent ground movement.

6 Testing:-

All lengths of drains and sewers installed correctly using the Plastidrain systemwill pass the appropriate air or water test. An air test is usually moreconvenient but an excessive drop in pressure may be due to a change intemperature, defective apparatus or failure in the pipeline. Should this occur awater test is recommended so that the leakage can be assessed and located.

Protection of pipes laid at very shallow depthsPipes may be protected at shallow depths using a 150mm thick reinforcedconcrete surround, with allowance for flexibility at pipe joints usingcompressible boards which should be equal in size to the concrete crosssection, or by means of reinforced bridging slabs of adequate strength.
