Product introduction
Asamaturewatersupplypipe,UPVCwatersupplypipeoffers robust acidresistance,alkaliresistance,andcorrosion resistance.It also provides excellent pressureresistance,high strength，lightweightconstruction，affordability，minimalfluid resistance,absenceofsecondaryollution,andcompliancewith sanitaryrequirements.Itsoutstandingperformanceextendsto convenient construction and operation.Vigorously promoting UPVCwatersupplypipesadherestotheguidelinessetforthby theMinistryofConstructionand theStateEconomicandTrade Commissionforthedevelopmentofchemicalbuildingmaterials. Italsoalignswiththegrowingdemandforimprovingpeople's livingstandards.
TheUPVCwater supplypipe systemhasbeenutilizedfor decadesinbothEurope andtheUnitedStates,establishingitself as themostprevalent andwidelyadoptedwatersupplysystem.
LessoUPVCwater supplypipesadhere tothePhilippine NationalStandardPNS65:1993.Theproductsmeetthe requirementsof thePNS65:1993standard andcomplywiththe relevanthealthandsafetyevaluationregulationsof theMinistry of Health.LessoUPVCwater supply pipefittings conform to the ISO1452-3:2009standardBasedonthepremisethatwateris fundamentaltohealth,LessoUPVCwatersupplypipescan replacetraditionalwatersupplypipelinesystems，effectively eliminatingsecondarypollution.Thisensuresthatpeoplehave accesstocleanandhealthydrinkingwater.
Lesso UPvC water supply pipes undergo rigorous testing to ensuretheymeetvarioushealthstandards,makingthema genuinelyhealthyandenvironmentallyfriendlynewproduct.

Pipe connection (Bonding procedure)
Selecta fine saw,cutting knife,or specialized PVC-Upipecutting tool tocut thepipeevenly and verticallytotherequiredsize.
Useaflat file toremove theburrandburredgeof thefracture,and createachamferattheend.Prior toapplyingadhesive,ensure towipeoffany residual debris,dust,water, and oil from the bonding surfaceofboththesocket andspigot usingadrycloth.
Useabrushtoevenlyandswiftlyapplythe specialadhesiveontothebondingsurfaceofboth thesocketandspigot.
Align the centerof thepipe andpipe fiting,then swiftlyinsert thespigot into thesocket androtate it by1/4circletoevenlydistribute andcure the adhesive.
Wipeoffanyexcessadhesivefromthesurface of thepipe using a cloth,and ensure to test the waterpressureonly afterallowing theconnectiontosetfor24hours.
