Venturi How to Make?

Answer

A venturi is a device that injects air into pond water to ensure adequate pond aeration, when making a venturi it is fashioned out of 22mm UPVC water pipe, with a corresponding 22mm T-piece and the central cone shaped restrictor hole is fashioned out of - wait for it - plasticine and again using the drill bit, constantly and slowly rotated, held loosely in your fingers, rotate it in a circular conical see-saw kind of motion with its axis at the centre of the T-piece, so that the plasticine is slowly squished out from both ends and then excess carefully cut off with a modelling knife and be careful to make sure the excess plasticine is trimmed sufficiently far back into the T-piece because if you don't, when the 22mm piping is push-fitted into the T-piece, it will squish the plasticine in again so ruining the shape of the cone just created. You may have to repeat the process for several times:- mould, shape, trim excess, until you are satisfied with it.

A venturi with a restrictor inside and above-water level air tube can be made with simple pipework and can improve pond aeration and water quality. Reference this link for venturi project information and instructions! leisure.prior-it.co.uk
Before making a venturi you must decide what size and type you want. You can make a pond, a mini-bio filter or a waterturnover venturi. Each one entails different parts. For more information look here: Instructions For Making A Venturi leisure.prior-it.co.uk;

The Venturi effect takes place when there is a reduction in fluid pressure, which takes place when the flow of fluid becomes constricted in the more constricted section of a pipe.
