This drain tube adapter fits hot tub pumps effectively, with customers praising "perfect fit" and leak-solving capabilities. However, some durability concerns exist—a few reported corrosion, breakage during installation, or premature failure within a year. Most found sizing accurate, though one noted the barb was larger than expected requiring hose modification.

Pump drain adapter

I spoke with your rep on chat and he told me the adapter that I would need based on my photos and pump model number. The adapter was properly sized on the threaded end that screws into the pump. The barbed end was twice the size of the original. I was able to modify the connecting hose to fit the barb. It all worked out with the modification. Overall, the order process worked well and the part arrived timely.

Is not corrosion proof.

Installed it and it corroded away in a month draining my whole hot tub in the middle of winter.

Hopefully I'll not have to be buy this item ever again.

Less than a year ago I originally replaced this same item on my new Hot Tub pump. This year the barb simply sheared off from the pump and lost most my water. Lucky for me I was home and noticed the loss of water. This year it was much more difficult to replace since the pump wasn't sitting on my work table but under the fixed one-piece formed body of my Dream Maker Hot Tub. Not sure why it simply failed after one year of operation. Hopefully it was just a fluke and a probable foreign manufacturing. Defect. Bought TWO this year just in case I needed to replace another, yet again, sometime in the future. I'm betting failure was a fluke incident. I hope.

IT'S PLASTIC AND IT BROKE WHILE SCEWING IT IN TO THE PUMP

IT'S MADE OF PLASTIC AND APPRANTLY CHEAP PLASTIC, WHILE TRYING TO SCREW IT INTO THE PUMP IT TWISTED RIGHT IN HALF.

This part fit well into pump, just a little snug. Just be careful when you start screw the part in. Easy to cross thread the part.

EXACTLY what I needed!

This item is nowhere to be found locally, including pool and spa companies. Thankfully the description for it was detailed enough that I was reasonably confident in it being the correct part. The part was shipped extremely quickly for their standard shipping, which I was profoundly grateful as my ""rigging"" to keep the spa functioning while waiting on this part was tenuous at best. I have found my go-to resource for future spa parts!

perfect fit in freeze plug.

Perfect replacement for replacing 3HP wet end on my hot tub's secondary pump when the motor bearing needed to be replaced. Cracked the impeller on the original wet end, so I had to get a replacement wet end (parts not available on the no-name OEM wet end).

you can't get by without this part

It is delicate and easily broken if you over tighten. I suggest you buy 2 or 3 just in case.
