This drain tube adapter receives overwhelmingly positive feedback for hot tub pump applications. Customers said it "fit perfectly" as an exact replacement, with many praising the precise fit. Some noted minor sizing variations requiring thread tapping for non-standard pumps. The adapter works well for bleeding pump systems, though one customer suggested including an end plug.

I would buy this product again - and I did!

Had the left jet pump go 4 years ago. Picked up one from Spa Depo for 1/3 of what the dealer charged and it went in and runs like a charm. Now, the right pump went so back to Spa Depot. Pump came in less than a week and I installed it that Saturday. Second time around it was a no-brainer. Back to Spa Depot for a fair price on a great product.

Exact replacement

Hot tub started emptying itself. It was a 9 year old fitting like this on the pump housing that disintegrated over time and blew out. This new one replaced it perfectly.

QUALITY PRODUCT

i THOUGHT THIS WAS A DIRECT REPLACEMENT FOR WHA I HAD BUT TURNS IUT THE FEMALE THREAD OF THE PUMP SIDE WAS SLIGHTLY SMALLER THAN A 1/4"" NPT. i TAPPED OUT THE PUMP SIDE AND MADE IT WORK.

EXCELLENT ADAPTER

SINCE I LIKE TO WORK IN A MESS FREE INVIORNMENT THIS ADAPTER WORKS GREAT. PROVIDED YOUR ENTRY AND EXIT SHUTOFF VALVES TO THE PUMP/WET END ARE WORKING PROPERLY.

Does not fit a Barefoot Spa motor

But, with a tap for pipe thread we made it fit. It was the motor not the fitting that was a weird size.

Right product, fit fine, no leaks

2002 Sweetwater Palermo - connection to secondary circulating pump. Works great, no leaks. Barb is not as long as the old one, but it seems to work fine. maybe a bit thicker than the old one (smaller internal diameter), but that may be due to plastic leaching of the old one (which is why I needed to replace). Replaced the associated lines as well, as they had become hard and discolored. With a handful of quick release clamps I was able to swap it out with minimal water loss without draining the tub.

HydroMaster Freeze Plug Tubing Adapter

Makes bleeding the pump/system a breeze. Would have been nice to pair this adapter with a plug to fasten at the end of the hose. I used a automotive vacuum plug to act as a plug.

Most Helpful!! LOVE these guys!

I could not determine the pump I needed on my own. I called, and was directed to email photos of my pump stickers. From there, Mark (Senior Technical Care Rep) told me exactly what to buy...sent me the links to the exact parts page for each part needed. These guys know their stuff, hands down. New pump arrived fast, and fit perfectly...worked like a charm. Took 10 mins to install. I am a homeowner, and not a tub repair guy. They made it REALLY simple. Next time the tub breaks...and it will...I know exactly who to call. Believe me, they will take very good care of you. True experts in this industry.
