Help needed - Gate valve modification to ASM G-6 skimmer

[Greg Hiller]

Now that I've got my new skimmer running, does anyone know how to do the gate valve modification that I've heard tale about so that I don't have the massive splashing going on as the water re-enters my sump?

This is a ER with the gate valve mod. Its the same mod for the ASM. You dont need that kind of gate valve either. One of the gate valves that ETSS skimmers bring will work just as well.

I could summarize it for you - you need some straight pipe, a T , a gatevalve and possibly a coupler in the same diameter as the output tube.

1. cut a 2 pieces of pvc pipe 3-4" in length you
2. pull the current riser off the output to the skimmer
3. attach the T to the verticle riser so that the T is installed like this |-
4. attach the gatevalve to the output of the T using a piece of cute pipe like this |--(gatevalve here)
5. add a riser to the top of the T to keep water from splashing out.
6. tune

If anyone is with more clue - feel free to correct me. I've only done it once, with Mark (Reef55)'s help.

You could also set it up as illustrated above by Casino. Although I think the top of that drain pipe is too high.
It's the same principle - you are looking to restrict flow on the output and have the drain under or near water to minimize splashing.

Heres one with one of the ETSS gate valves. You dont need the unions either since all the PVC is slip. You do need the gate valve to be slip X slip

This is a pic of mine. I think it is the same mod you are talking about

 

[Casino]

This is a better pic. As you can see theres no unions or nothing everything is slip X slip and it has a gate valve

Nice! Greg you went with the G6

if you put the output at an angle and submerged it'll help with the splashing too. this worked on my g3. i think i have the output down at like a 30* angle and then a 90* aimed back up on the end, makes the water exit a bit calmer

 

[Greg Hiller]

Thanks all for the response. I clearly had it set up wrong. I'll pick up a 1.5" tee on the way home.

Looking at Casino's photo again there is a potential failure mode that would allow/force all output to flood the skimmate container as there is only one way for water to exit it. Flighty's setup is safer and similar to what I described. If the output is blocked, it will just dump out the top of the Tee

Because of the size of my skimmer I couldn't do the mod the way it is showing on those pictures.
I had to do like the on bottom right hand corner of the ASM modification Page

let me know if you need a clearer picture of mine. I can get one from a better angle.
