Backwash plumbing question

[Fathead657]

Im still new to owning a pool with this being my first full summer. My pool is not used much so back washes are few with an autocover keeping stuff out.

My question is about vacuuming to waste. I did this for the first time this weekend. my water runs from filter through about 6 feet of pvc to 4 inch corrugated, non perforated drain tile.

After vacuuming for 15-20 minutes I noticed that between my pool equipment and pool decking (20foot area) there was water on top of ground and surrounding area was soft.

Is this the wrong tile to be using or was it installed incorrectly? Ive been looking for local/state codes but cant seem to find it anywere.

Your basically dumping the water to daylight in front of the equipment so then what you have is to be expected but probably not recommended. I'd extend the drain to lead the waste water away if possible and let gravity help it along too.

it is tiled away already. pvc pipe dumps into the tile and away. thats why i have the concern that 20 feet away from the pool mechanical pad where the pvc and tile connect i have saturated ground with water on top of dirt. hope that makes more sense. i can try and add pictures this morning after I get home from work

You can call it a drain tile but you're talking about a pipe. So you're saying that the joint between the two pipes is leaking? Then you need tighter fitting pipes or you could wrap some tape around the joint. It could also be that the second pipe isn't going down hill from the first so the water is seeking the low point. You could just get a rolled up discharge hose from a pool store and clamp it onto the 2" pipe from the valve. Then roll it out to where you want it. That way you could also move it to other areas around the yard if needed. The hose can be extended with another hose clamped together with a short piece of 2" PVC.

Where the PVC and the drain tile meet there is no water. It’s dry over there somewhere along the path of my tile. I believe there’s an issue because I have water on top of my ground from when I was vacuuming to waste. There’s no other reason for water to be there other than I was trying to drain water.

If water is sitting it is not draining. Is the slope correct? Is there a blockage farther down the line? Where does the drain tile terminate? if just into the ground you need to extend the line to where it can flow out as the ground is saturated, or quit vacuuming to waste, vacuum into the filter and then backwash. That definitely uses less water.

According to the pool builder who said and I quote, I know hydraulics says it the slope and grade of the tile is right when he put it in he doesn’t know about this problem yet I’m trying to find out mostly is it supposed to be in a smooth pipe regardless of size instead of the corrugated field tile that’s used for the drain? I’m gonna add a picture where you can see my mechanical pad in the background and then they’ll be a red arrow where it shows where the water was standing, and then the second picture will be the water standing in the ground saturated

Hope this makes more sense rather than trying to type it. I work nights so I won’t reply again to you until this evening.

Are you draining into a weeping tile? The grill in your pic is right next to the house so if that's supposed to be an exit for weeping tile it is incorrect. If it's a drain instead then does it go to a lower spot beyond the yard? If you're draining into the yard somewhere and it slopes to the house there's nothing you can do without regrading the lot.

Its a grading issue but can you show a picture from the tank towards the house.

 

[Fathead657]

I can tomorrow if by tank you mean my propane tank. I dont know how it can be a grading thing though. There is now water flowing on top of the yard anywhere. The drain tile goes into the ground and is at least 10 inches under my grass and drops down at least 6-8 feet by the time it goes across my yard to the field

 

[wireform]

If I'm reading this correctly 6-8' deep? Then the water is leaving the pipe at a jonction/connection point. Again, if there's water all over I would say the grade is ultra flat so the water just hangs out instead of getting away. Firstly you need to determine where the water is exiting before you try to find a resolution.

That’s my concern over 70% of the tile is under concrete. Don’t ask it makes me upset.

Here are a few pictures looking from where drain exists back towards house and mechanical. the tile does have water exiting it when vacuuming

One from tank as requested

Arrow in first picture is where mechanical is from drain exit. Arrow in second is of drain exit area from tank. Third is of how the pvc enters the drain

 

[Fathead657]

Here’s the third. Off to bed thanks for the time you spend helping me

It looks like it goes uphill before it can go downhill.

 

[Fathead657]

In the pictures I can agree. But if that was the case would let water come out up by the pool mechanicals?
