is it ok to submerge drain pipes with Durso's?

[mattseattle]

I was curious if it's ok to put over flow drain pipes below the waters surface in your sump? I'm using Durso Standpipes and was wondering if that would then create back pressure. How do most people have their drain pipes? an inch or so above the water surface draining into a filter sock?

Thanks for the tips

Matt, I run mine just below the waters surface. On my new setup the drain goes all the way to the bottom but it has slits cut in the pipe to let the water out, it seem to work really well also. Here is a picture of the slits, I’ll take a closer one latter if you want.

ok, i see how you are doing it.

hey are you going to gravity feed your skimmer?

hey are you going to gravity feed your skimmer?

Yes it is setup that way now and in the picture.

ok, then i have a question for you. are you getting any bubbles into your skimmer chamber from gravity feeding your chamber? when i did my leak test yesterday i noticed that a few large bubbles are entering the skimmer chamber. i've read threads where they say large bubbles are bad then i read other threads where they say it's normal for some large bubbles to enter from the overflow. 95 - 96% of the bubbles are exiting via the T on my plumbing and entering the sump instead but i do have some entering the chamber.

just curious how yours was...

I was getting a ¼ - ½ inch bubble every half second or so entering the skimmer (this is with tap water). The bubbles became less frequent after a few minute of testing. I’m sure that the bubbles I’m getting are ok, and will not affect performance.

I think it’s more about getting the correct flow thought the skimmer and the right amount of air. My skimmer is plumbed directly to one of the two overflows, no tees and no valves to the skimmer. I do have a valve on the other overflow so if I want to increase flow to the skimmer I could just close it a little. My return pump is pushing between 700 – 750 gph to the tank so I’m getting 350 – 375 gph to the skimmer. The max rating for my skimmer 475gph. So at 350-375gph it is running a little slow; however I think this is a good thing.

Hey there dieseldave.......

you might (REALLY) want to be moving your tools away from right next to the remote sump, I've run into rusting problems from tools and steel structure near my tanks I've run in the garage in the past. It's amazing how toxic the salty air from evaporation can be.

Keep a can of WD-40 near by and keep your tools drenched in it as a minimum.....something to think about.......

Hey Rocky, I have a lid that will be sealing the sump to cut down on the evaporation, In the garage. I'm sure there will still be some but it should help.

PS. you still need to come over and have a look for some trading.

Sorry for going off topic Matt.

i don't mind off topic stuff

thanks dave for the input...i've also read it's more about flow and air in the skimmer. i think i'll be ok as well.....

thanks for helping me out!
