Greetings,
I discovered a leak at the outlet hose at the bottom of the filter housing. The filter housing is not leaking. There is a 2 inch long flex pipe at the bottom of the filter housing. Attached to this is a plastic "T", with one end going (I don't know, probably to the pump) and the other end to the drain valve. The leak is where the 2 inch outlet from the filter housing connects to the top of the "T" fitting. So, how do I go about fixing this leak? I imagine that I will have to drain the tub, and cut out the "T" and then replace it. Where do I buy parts and glue and all the goodness required to make the repair? Is there any easier way (you know, the magic goo that fixes everything?? hahaha)

Thanks,
Stuart

Ahh you are about to embark on the worst nightmare possible! (just kidding) Granted, this job is by no means fun. Well, I suppose for some it might be! The proper way to fix this is to replace the "TEE" fitting. Most of the time you can get away with just cutting it out, right at the "TEE" and then using 3 couplers, 3 bits of pipe, and the new "tee", you can often just replace it. However, since yours is leaking at the bottom of the filter housing, you're in for a treat. It won't be so bad if your leak is at the tee, since you should have enough of a "nub" of hose to attach the new parts to, but if it is at the housing, you will have to cut the flex hose between the two, and carefully (CAREFULLY) carve out the flex hose from inside the filter housing. This will take a long time. Otherwise you will be looking at replacing the filter housing as well. You can try using silicone to cover up the area, but this is most often temporary, if it works. Another trick you might want to try is to slowly build up the area with standard PVC glue. Sometimes this works, sometimes it makes a bigger mess then it's worth. There is a special PVC glue for flexible hose, so when you get to the point of attaching the flex hose to the new "tee", use the special glue. And remember, make sure you clean the old and new parts with the appropriate cleaner for the glue you will be using, before you apply the glue. A word of advise: on old flex PVC hose, I find if you scrape the surface before cleaning with the cleaner, you get a much stronger bond. Everything you need can be found at a Menards store, maybe Home Depot (ours doesn't have the flex glue), and possibly Lowe's (stores like that). One more note, if you don't have at least 3/4" of hose to glue to, keep replacing parts until you do. I found anything less than 3/4" will hold, but only for a while.

Thank you very much for the information (even though it wasn't for me) this was exactly my question! I hope I can find the glue. Thanks again!

Ok, I wasn't hitting on all 8 cylinders that evening.... glue can be found at any home improvement center

Mine is also leaking(gushing) from the hose where it connects to the filter housing. However it just appears that the hose came out. It isn't cracked or spilt You can see the glue line where it was conected.

So I pushed the hose back up in there and now I need to clue it. All connection one this spa are glued with what looks like clear silicone, exept its hard not soft. What king of glue is that and is that what I have to use to glue the hose to the filter housing?

If it's hard pvc then you use standard pvc primer and cement, if it is flexible pvc then you need to use flexable pvc primer and cement. Make sure you use the primer, and if possible, try to scrape as much of the old glue off as possible.
