Hi TFO folks,

A pool company started a liner replacement. It was riddled with holes and rust was starting to show. While we were doing the work we figured we redo the pad with new everything, along with the plumbing, as everything was either broken, inefficient or sounding sketchy when running. Like replacing a non-functional in-line chlorinator (I'm a liquid chlorine guy anyway) with a SWG with Omni S3. I also had to repair a cracked step 💸💸💸

Saturday was liner installation day. They also installed the SWG and replaced the plumbing. They pumped out whatever water gathered up from what we thought was from the recent rain. It was here they realized that the ground water is seeping in, maintaining a constant 1" worth of water, even with 2 pumps running. I do have an "excellent well" and I am the downward side of a hill, so it's not surprising I am seeing water seeping in.

There are two flexible pipes coming out of the ground, but trying to use them to pump, nothing was happening. They could be clogged, or no dry well is there. Or they may not be for a drywell, he doesn't know. (Photo attached).

The pool is about 20 years old. I'm not the original owner, we bought the house in 2023. From the two years we've been here, I'm finding either the builder cut corners or the previous owner did. Did 20 years worth of Crud gather in the well because he didn't do anything for it? Did the pipe collapse? Did a rodent make a home in the pipe? The pool installation guy believes he was here once before to repair a lifted liner after a heavy rainstorm, but not 100% sure. We've had some very wet winters where my sump pump was pumping out gallons every minute, yet did not have an issue with the liner when we opened in the spring.

At the end, the company is quoting me $4500 to install, pipe and pump the drywell. I'm stuck, because they will not install the liner with water at the bottom, and my backyard looks like a run down road side motel. That's still on top of the other costs of installation as well as tankers for water and the electrician to wire everything up. Then there's other, unrelated recent house work that also went a bit sideways. I'm just...exhausted.

The only bright side of this is that it may give me the opportunity to put in a bottom drain, as I only have 1 inlet and skimmer, both at the same area of the pool. That variable speed pump won't have to work as hard, and there would be better circulation, I guess. Still have no idea how much that would cost, but in theory it shouldn't be that much, it's just running another pipe, right?

I guess I'm here for everyone's thoughts, like is there anything I can do that I'm missing or wasn't explained to me properly? Or this is just something that has to get don

Or maybe I just need to vent and get a bit of emotional support, because I'm just about done with people...contractors specifically.

PS: Ignore my signature. It's about 24K gallons in a 12x24 pool. I just need to figure out how to fix it on a mobile device.

There is a lot here to unpack. Why does this give you the opportunity to put in bottom drains? What is an "inlet?" I don't recommend people put in a main drains in a vinyl pool...way to many issues to deal with and they are unnecessary. Not sure why you think having drains will make the pump work less hard...a pump works at the speed you set it and will move a certain volume of water depending on the head.
 
Show us picture of the pool or the hole in the ground.

I would put in a second skimmer before a main drain. A pool does not need a main drain and it will not benefit you much. A second skimmer will help your circulation more. Especially if properly placed.

I apologize for the terminology. When I mean inlet, I mean the return to the pump. Is there a specific term for that?

Attached photo shows the plumbing situation. Left side is the pump return (in the rust). The only skimmer is nearby.

On the right is the pool return. Not pictured behind me are spa jets. Otherwise I don't really have any circulation below 2 feet, other than a robotic vacuum, use, and occasional brushing.

As for a drywell, that hasn't started yet. They basically are saying either dry well or no install (or figure out the water situation).

You don’t need a bottom drain, but I would do something to keep ground water away.
