1）In our PI we have already made a remark that our tub water-in & water-out thread is 1/2" female tread Customer needs to buy correct hoses to fit our 1/2" female threads 2) Also in PI obviously a remark of our product accessories include lid,handpump,bag and repair kit. NO VALVES AND ELBOWS .Icebath tub can be used without valve.If customers want vavles,they need to buy by themself or tell us before shipment, we can provide these accessories. Let me reiterate that valves and elbows are not standard accessories ! Just like you buy a car, but there's no children seat,if you want a seat, you need to buy one!
