Hose popping off

[t-cal]

So happy to have found this wonderful forum.

I have a new (since June) above ground pool. This morning found a hole in the hose that connects my filter to the chlorine dispenser. Pool had drained to below skimmer and don't know how long pump was running dry.

I purchased a new hose (of course it's not the same one that came with the pool, but a replacement hose), filled the pool and tried starting up the system again. However, the hose keeps blowing off the fitting to the chlorine dispenser. I can see the pressure building in the hose and then it pops off the dispenser.

Called the pool store who said to soak the hose in hot water so it fits further on the fitting. It fits in the same spot as the former hose.

I just cleaned the pump, filter cartridge, checked chlorine yesterday. Could I have done something to cause pressure to be building up somewhere? Before the hose pops off I do notice that water is coming out of the return into the pool (but didn't get to check how strong before the hose flies off).

Thank you.

Sounds like they sold you the cheap hose and connectors with the pool, try tigerflex and barbed connectors. Besides that, maybe 2 clamps instead of 1.

I agree with Matt, you may need better clamps for this new hose

Thank you both, so much, for your prompt replies.

I was just out looking things over and seems my husband (of course I'll blame it on my husband) put the prevail chlorine pack in the dispenser backward. I think that is causing the pressure. The pack also seems a bit "pinched". I'm going to replace the pack.

In the meantime, the hose is not popping off, but really expands big time. I am hoping that is normal, as my previous hose did not do this. This one seems a bit more flexible.

I know it's a stupid question..... but should the hose expand once I turn the sytem back on.

I've never seen a hose "expand" before, on my pool, they just look like they "stiffen up" some with a bit of movement, but then they equalize and settle and look the same as always. I'm not familiar with the Chlorine pack you're describing since I only use bleach, so I really can't say whether that is part of the problem or not.
I wouldn't trust it not to pop off again, not something you want happening when you're not around, I would look into it a bit further because it just doesn't sound right.
Can you run without a chlorine pack and see if the problem goes away?
A chlorinator should not give that kind of backpressure to expand a hose.

matt:

Actually, I did by-pass the chlorine system and go directly to the return. The hose seemed to be fine. I think I was being a bit overly concerned with the movement of the hose. It's just a bit more flexible than the original hose. I will look into the hose and clamps recommended earlier. In the meantime, I'm only running the pool when I'm around to keep an eye on it.

I truly appreciate everyone's responses.
