4 Inch Aerated Bottom Drain With 12″ Diffuser
Without any doubt the best Aerated drain on the market today professionally manufactured using the latest state of the art machinery unlike many just being hand cut……!or other examples that require the use of flexible pipe inside the drain which at some point will need replacing…..!
The best selling Aerated drain on the market,why because unlike any other it utilises a 12 inch EPDM rubber diffuser top giving far more aeration and pulling efficiency,also the only drain on the market with 0ver 60mm between the 4 inch inlet and top flange which enables you to lay a greater depth on concrete over the pipe….. no other drain does this, it also still has the best rubber air diffuser out there which can take far greater volumes of air when needed.
This drain has a solid 1 inch air feed and at no point requires you to use flexible pipes etc to connect air inside the drain just simply connect 1 inch solvent solid pipe from the back side of the drain and run along the side of the main 4 inch drain pipe and terminate outside the pond.
Exclusive designed for Coastal Koi this bottom drain now has the very latest 12″ Gummi Jager diffuser the World leaders in this field.
Has a 1″ air feed direct to the diffuser, eliminating flexible pipe
The diaphram can handle 200Ltrs we recommend between 60-80 Ltrs this will also depend greatly on the depth of pond
A real must have for any koi pond,its built to last has a 4″ pressure pipe outlet but can also be used with 110mm waste pipe where a reducer sleeve will be required.
In our opinion the best on the market, fully tested and works superb and hundreds and hundreds sold over the years.
Available for concrete or liner ponds.
Also please note you will need 1 inch pressure pipe 3 x 1 90 bends and 2 x 1 inch 45 degree bends when plumbing this drain in.
