Why not? I’m fitting one tomorrow. 1st time. Expense?

they dont do the claimed flow rate

 

[Harvest Fields]

They cannot take the full pressure and overflow.

Thought so. Only info I could when searching HDPE seemed to refer to fusion weld.

Two types, two flow rates.

Im not sure i trust those hotuns either. Not sure how well they will perform in a few years time if that spring inside rusts.

When i spoke to vaillant about this they were happy for it to be setup like this as a last resort. The plastic isnt PP but its PVCu hight temp solvent weld.

Is high temp solvent weld different to a standard solvent weld? So is that black pipe in the picture standard solvent pipe?
What is that adapter that the tundish is fitted onto?

Most solvent weld sold is ABS which doesnt have a high temp rating, the pipe in the pic is high temp PVC C even. Which osma superceeded MUPVC for i think. Tundish is on a hepvo with "tundish adapter"
