Hello, I would like to place a RFG on 3/4 inch PVC pipe, what do I need to accomplish this?
currently the only way to achieve this would be pick up a PVC female adapter such as this

then add a 3/4in Loc-Line NPT fitting

and then the 3/4in RFG nozzle would snap onto that. You could also add a few segments of 3/4in Loc-line between the NPT nad the nozzle

how hard is the RFG to install into a locline? would i need a tool or a simple push will do?

Thanks
@TheHarold is correct - we desinged the RFG to be easy to snap on genuine loc-line with very little effort. They are also just as easy to remove for cleaning. However, when removing them don't pull straight out on the nozzle, but rather pull to the side, like you're snapping a twig. This will pout the elast amout of stress ont he nozzle and ensure they last as long as your tank.

Hello. I have 2 of these for each of my 1” returns, which will come through the top of my overflow weir.

I’ll be pushing about 1200-1300 gph through each.

I just read in another thread that the tops of them need to be 3/4” below the water line.

My initial thought to accomplish this is that I’ll need to notch out the weir a little lower and have my returns not quite as tall. Alternately , simply cut a 1” circle in the overflow where the return comes out, push the return through, and attach the RFG on the other side.

Should I be drilling a siphon break if I do either of these? Where?

HI NAtD - thanks for the questions and i apologize fow the the slow response.

The depth will depend the nozzle needs to be will depending on both the size of the RFG and he flow rate. If hey are 3/4in in RFGs then that depth sounds about right. if they are 1in RFG, them you may be bale to get them a little closer to the surface surface . the measurements are based on Position B on the diagrammed in the first post

As far as how you should adjuster you current setup, a few photos might help me better understand what you're dealing with, Can you post a photo of the wire and return?

Hello! The good news is that I haven’t plumbed the returns yet! We are fully flexible. They are 1” returns.
I’ll check out that diagram, thanks.

Currently running 4 of the 3/4 rfg nozzles on my 180 gal powered by a jeabo dcq20000 return pump. Im very satisfied. In fact so much so im planning to run multiple of the nozzles on a double closed loop system on my 300gal build.

Can I get the minimal and optimal flow rates for the 1.5 RFG?
Sure

Single 1.5in RFG
- Minimum: 900-1000
- Suggested Optimum Flow: 1,500-2,000+

As with all RFG nozzles you, the Suggested Optimal Flow is where you we feel you'll get the best randomized flow for the least amount of back presure. You should expect around 10-15% max at that rate.

If, however you OK with some additional throughput loss, and you have some pressure to spare, you can really get things rocking with more pressure and more flow.

here's video we did last year that shows just that, with some of our larger RFGs in a pool

Unfortunately for these tests , we didn't have any way of measuring the actual flow rates, but it was with an Abyzz A400 at varying levels of power.
