Slip-on tub spout leaking

[Mr Fixit eh]

I have a new Riobel Equinox EQ80 tub spout on 1/2" copper. When the tub is filling, a good stream of water comes out of a 1/8" drain hole on the underside at the back, near the wall. It was just a slip fit over the copper - I'm thinking there should be an o-ring to make a seal. Any suggestions?
Of course tech support won't be opening until after the long holiday weekend.Leakage through drain hole

I should add that the tub spout does not have a diverted. That function rests with the mixing valve.

That style spout connection, utilizes an 'O' ring to provide the seal around the copper stub out.

Remove the spout to inspect the 'O' ring inside. Your spout's 'O' ring maybe missing, or may have been damaged during installation, particularly if no lubricant was placed around the copper pipe stub prior to sliding the spout onto it.

The proper lubricant for 'O' rings is silicone based, not petroleum. Most hardware stores carry a silicone based grease type plumbing lubricant such as shown at the link below.

The 'drain hole' is not intended for that purpose, but is where typically a hex Allan Key will be inserted to loosen/tighten the mechanical clamp which fastens the spout to the copper stub.

Thanks for the reply.

I did not notice an o-ring on initial exam, but I did not study it closely. Any idea where the o-ring should be - near where the 1/2" pipe inserts or at the back?

I do remember at the time that there did not feel like there was any tight engagement with the pipe, it was just a loose, slightly wiggly fit prior to snugging up the hex keys - there are two - one on either side of the 'drain hole'.

I pulled off my tup spouts to replace them but I'm having a hell of a time. The spout pipe types without threads on the end so I'm just sliding the new spout on and tightening the screw on the bottom real tight with an Allen wrench, but water leaks out the back of the spout on the shower wall. Normally this wouldn't bother me but I'm afraid the water is just shooting back through the hole in the shower wall and into the wall. Am I missing something? There is a rubber o-ring in the new faucet that's in the correct place but no matter how tight I make the screw water just sprays back out and it's even worse when I divert the water to the shower. I've even been trying to put the old faucet back on since it worked before I took it off but to no avail. Any ideas?

In my case (above), it turns out that the instructions were very poor combined with a fault in the spout, leading me to cut the tub spout 1/4" too short. As a result, the o-ring didn't make contact with the 1/2" copper.

Luckily the manufacturer has another model that is similar in design that accommodates a 1-1/2" stub out which they are sending to me without charge.

In your case, if the copper properly mates with the o-ring, make sure the o-ring is not damaged. Also, don't over tighten the set screw(s) so as not to deformed the pipe.

No you didn't
