I had been unhappy with the amount of water flowing down my falls this year. Last year there seemed to be a lot more water flowing down and I was using a bigger pump this year. Last year the pump would only take 1" ID hose with a hose barb but I used 1 1/4" hose and slipped it on the threaded outlet. Well I did some checking about my new pump (Tetra 3600 high flow magna drive) and figured out that I could use 1 1/2" PVC pipe. Finally got it done today. Will post pics later on how it turned out. I also took the time to fill in some gaps with waterfall foam since I had the pumps off.

As I said earlier...here are some pictures..Sorry they are so big.

This is coming out from the top of the pump and thru the skimmer box. I did all of the pipe in 1 1/2" PVC

I tried to use as many long sweep 90s as I could, but there were 2 places I didn't have room

This is looking from my skimmer box up towards the filter. Its not flat ground so it was a bit of a challange to get the pipe to lay the way I wanted it to

This is coming into the top of the skippy filter

I even added a venturi. Works great and it was easy to make

And this is what I used to get my pipe to bend. When I was a electrician, we used a thing called a hot box to heat up our pvc to make bends in it. I just heated up the pipe on my grill, ran over and formed it how I wanted it, let it cool and moved on to the next section. I used one 10' piece of pipe after getting out of the skimmer box area up to the filter.

Yes grill was on high and I had the lid closed turning the pipe constantly.

WB...sand would take too long to heat up. The only time we used sand when bend pvc was on 4" and bigger. I did commercial electrical work. Mostly new construction and mainly schools.

I still have to paint the pipe and then hide it. Took about 2 hrs to do all the pipe.

Explain your venturi, looks like a cap with a straw sticking out of it! What steps did you take to do that?

It's a regular plumbing wye with the water flowing thru the straight part. I cut a small piece of pipe to glue the cap on. I used a straw from a cup we got from the hospital. I drilled a 3/8 hole in the cap just big enough to put the straw in. I stuck the straw in so it was half way in the straight part so that as the water flows thru the pipe, it will suck air in and aereate the water as it enters the bottom of the filter. The good bacteria will then have oxygenated water to feast on along with the plants in my skippy.

Adding a check valve should be easy enough to do. Put it right before your last 90 degree that goes up and over your filter. I used a sump pump check valve for my bog.

The venturi should break the back siphoning effect out of the filter

pool hose works and so does sump pump hose .It depends on the size you need .I have been using sump pump hose ,cheap to replace and since it does not get to cold here most times it works good .Been using it for over a year .Pool hose is stronger and can take more abuse .It would also depend on your winters and if you are going to change things now and then .I find it easier with flexible hose for me ,but thats me ,not every one .

I used a pond pipe that is called Tiger flex [from USA I think}. Costs more money but is well made and thick walls. Yes a cheaper flex hose at H-depot for example might have collaspe issues or leaks etc.

Brandon that is awesome I had no idea you could bend PVC like that! Saves on couplers and angles huh? I've been wanting to move my filters to my garage, that will be a great way to do it? I also see that you do not have the pipe buried, can I bury the pipe or should I find a different place to run the pipe? Could I use the venturi on my up flow bio, haven't started my bog yet :( hopefully soon.
