Cool thanks guys.... I have one long run from the skimmer.... Its about 10m, but relative to what size most pools are, its not very long... That makes me feel better...
The trade off for plumbing ease however, is 2 inch hose is a little more expensive than 1 1/2' and so are ball valves, but it means I don't have to do any complicated plumbing.... My pool has two suction sides, and one return as per Aussie regulations..., I plan to add the skimmer, turn one of the suctions into another return, so I will have two suctions and two returns...
Nothing too difficult, so all I will need are 4 x 2' ball valves, 3 x 90 degree 2' pvc elbows, and about 20 metres of 50mm pvc hose... And about 12 x 2' stainless steel hose clamps.... Too easy....
And to bother you good people again.... If someone could tell me the plumbing I will need, in order to add my 3/8' peristaltic pump hose directly into my soft pvc hose return, that would be awesome... I am not sure what parts I need... Any advice is appreciated...
