Kink-Free Pipe For Water Gardens & Fountains
Note: A good way to think about tubing size is to imagine drinking from a straw. If you were to try to drink a glass of water with a cocktail straw it would take much longer than if you were to drink that same glass of water from a standard size straw. Over the years we have developed a chart to help our customer's size their tubing. Please see below.
Up to 500 GPH: Use 1/2" Tubing Up to 900 GPH: Use 3/4" Tubing Up to 1,500 GPH: Use 1" Tubing Up to 2,700 GPH: Use 1-1/4" Tubing Up to 3,600 GPH: Use 1-1/2" Tubing Up to 5,400 GPH: Use 2" TubingUp to 13,500 GPH: Use 3" TubingUp to 21,000 GPH: Use 4" TubingUp to 42,000 GPH: Use 6" Tubing
Plumbing Tip: Try to avoid 90 degree turns for this will cause friction slowing down and reducing your water flow. We always recommend Flexible piping instead of rigid piping to avoid connections that can not only leak but cause friction loss reducing your water flow.
Proper plumbing is very important!!!
Your pump can only work as well as your plumbing system allows it to. A larger pump does not always mean more water. A larger pump and larger pipe does mean more water. You can only fit a certain amount of water through a certain size hose.1"hose= 1,500gph 2" hose= 5,400gph 1-1/4" hose= 2,700gph 3" hose= 13,500gph1-1/2" hose= 3,600gph 4" hose= 21,000gphFor example: If you have a pump that is rated for 7,200gph and you are using a 2" flex hose. You are only going to get about 5,400gph coming out at the end of the pipe. Yes, head height, elbows, etc. have a factor in it also but I am trying to keep it simple and make a point. If you need more GPH, try using 2 hoses or upsize to a larger diameter hose.
