Intex 15110-1 leaking

[Poolsarework]

Hello,

I have an Intex 15110-1 sand filter combination pool system. I hooked it up for the first time this season a few weeks ago and noticed it was leaking around the pre-filter housing assembly. I ordered a new pre-filter housing and new gaskets and the problem is still persisting. I will post a video later. Any help or tips are greatly appreciated. For some reason it seems like I am missing a gasket. The troubleshooting tech said I would have everything that I needed though.

Welcome to TFP! Are you referring to the pump strainer basket/pot with the clear lid? There should be a rubber O-ring under that lid and it should have a good amount of pool silicone lube on it as well. Something to check.

I'm taking about this spot right here. What am I missing because it doesn't make sense according to the block diagram for this model.

The only thing I'm seeing for that area is the pump inlet O-ring that goes in there. I"m assuming you had one?

Yes, there are actually 2. Brand new.

What kind of leak are we talking about... a drip, a stream? Are you sure it’s not coming from somewhere else and channeling to that point?

It's probably losing 10-20 gallons a minute. It's definitely coming out from where the picture indicates.

When I initially fill the pre-filter there is a slow drip. Once under pressure, it gushes out. It's near impossible to get on the phone with Intex as well and the previous owner is unsure of the cause as well.

Odd. There shouldn't be pressure there, that's the inlet. I would not expect the leak to get worse with the pump on. If anything it should be sucking air in.

Are you sure your valves on the pool inlet and outlet hoses are open and the 6 way valve is correctly positioned?

My pump looks a little different but I have the double O-ring seal you mentioned.



There's nothing there that should be under pressure with the pump running...unless the pump housing is cracked.

Can you remove the pre-filter housing and inspect the pump body under that for cracks?

There are no cracks. Pump is in filter mode. I'll double-check again this evening to make sure the valves are in the right position.

After further investigation, there is a small hairline crack right along the inside seam of the inlet pump cover. Dude, thanks so much for the insight! I thought I was going crazy. Minor oversight can cause a huge headache for sure. Time to grab the towels and Mai Tai's!
