Hola my favorite site that my wallet hates.

Here goes the short version of what I hope will be the eventual end to ALL my problems (it won't, but a guy can dream)

I've got a 30 year old pool that has a leak in one of the suction side lines under ground somewhere (Pic of pool attached for reference, yes it's dirty but that's not today's concern). This leak is introducing air into the system, which we confirmed doing a pressure test a while back.

I've had 3 or 4 pool guys out, and a licensed plumber. They all confirm "Yup, you got a leak". Here's my dilemma. If I'm gonna be digging up the backyard for one line, we might as well do the whole shebang and get it over with. Piping starts just off the right of the picture, and runs under my concrete decking to 2 skimmers and 4 jets.

When I had the pool guys/plumber out, I never did get a complete price quote, but I got a ball park of $10k. I may not fully understand the complexities involved in replacing the entire plumbing, but I just can't fathom how it could be that pricey. Paying for connivence sure, but 3 guys, a ditch-witch rental, maybe a small Cat rental, and 3-4 days of labor just doesn't seem like a $10,000 job. Keep in mind, that price was not to fix any of the concrete that has to be cut, or replace my well aged marble walk way. This was straight "cut where you need to cut, dig em up, plop em down, seal it up, and back fill with dirt"

Has anyone taken on this level of renovation with a pool company? I'm almost thinking if that price range is right, it may be a better idea to subcontract out the cutting/digging, bring in a pool company/plumber to run my lines, and back fill / replace concrete myself.

It basically goes like this. If I'm gonna be replacing the pump itself with a new variable speed (mine is on its last leg, and old enough to not really mind the cost of a new pump), then I might as well replace the tank too (same age as pump, seen better days). If I'm going that far, then I might as well go with the bigger pump as I would like SWG in my future, which requires 2 inch piping. Once we get this deep down the rabbit hole, a full plumping renovation doesn't seem so bad. Keep in mind, the 10k number I threw out was ONLY for the underground plumbing replacement. Pump, tank, SWG, etc on my equipment pad would all be separate and extra

Any tips/info on pricing would be awesome. I'm not against a fair price, and a job well done. However, it needs to make sense in my brain to plop down that kind of cash

I would start with getting a pool leak detection company - that has special equipment to pinpoint exactly where you leak is to start.

It could be just one skimmer and that would not be a huge expense to fix.

No reason to demo your entire yard and pool if you can target and fix the leak.
 
Patrick,

While I was trying to find a way to politely tell you that your plan does not sound right to me, the two "In the Industry" guys above have stolen my answer... :p

Jumping from "Yep, you got a leak" to re-plumbing the entire pool just does not make sense to me..

Kind of like going to the doctor for a ingrown toenail and the first thing the doc says is "Let's amputate the leg just below the Knee"... Just a tad of an over kill... :D

Do you know where the leak is?

Do you know how your two skimmers and main drain are plumbed together? Do you have individual valves for each one or ???

Is the leak so bad that you can't run your pump or ???

How about posting a pic of your equipment pad...

Thanks,

Jim R.
 
10k for demo & replumb is not unreasonable, if a full replumb is needed.

I would opt to replumb everything if all pipes are shot, old copper or planning new decking in near future.. otherwise the surgical approach would be the route to travel.
 
We paid $7500, for new skimmer, new drain lines from skimmer to pump, two new return lines in different places, two new deep end drains, ran all the way through the shell. (We also remodeled the pool though, and had the concrete removed by someone else) your quote definitely seems on the high side.
