I have a big barrel that collects rainwater and has a submersible pump
in it to pump the water out when we want to use it.

I'd like to fit a tap to the pump outlet that comes through the side
of the barrel near the top but I can't work out a simple way to plumb
it. The pump outlet (when it gets to the top of the tank) is a 22mm
plastic pipe which runs horizontally to the side of the tank.

Thus I need a tap to mount on the relatively thin side of the barrel
with a 22mm inlet and, preferably a 3/4" BSP on the outside for hose
fittings.

What's the simplest way of doing this?

I assume you want this below the water level (and thus sealed)?

I assume it is a plastic barrel, is it open topped or if not is there a
reasonable sized access hole in the top?

Basically your Google search term is Bulkhead fitting.

Well, at the surface, but it's just a mechanical fix I want really, it
doesn't *have* to be watertught.

Yes, it has a huge removable lid so access to inside is easy.

You want a bib tap plus a back nut. And a washer.

.... but doesn't that just fix the tap onto the barrel, how do I feed
the water from the 22mm pipe into the tap? ... and aren't most/many
of those taper threads on the back of the tap?

Not answering your query, but from experience with plastic water
butts, fatigue cracks develop around the purpose-made tap attachment
point after a few years. I imagine this would be worse on thin
sections of the wall not intended to have a tap. I would suggest that
you try and reinforce the butt wall in the area you intend to fit the
tap to try and reduce fatigue cracking.

If I could find a way of simply feeding the pipe securely through the
wall of the barrel that would probably be sufficient but the prices
for 22mm straight bulkhead fittings seem exorbitant. About the
cheapest I can find is:-

Almost £25 including carriage.

I'm not sure that I fully understand what it is that you want (too long in
The Malt Shovel Tavern is my excuse), but something like:

Or, possibly, an IP66/67 25mm electrical grommety thingy might compress down
enough to do it.

OK then, just feed the pipe through a clearance hole, secure with a
cable tie inside and out, and cover both sides with a fillet of silicone
or mastic. If you think you are going to apply large forces to the tap,
get the type of tap which is designed to be screwed to a wall, make up a
wooden saddle, fix it to the barrel with screws and washers from inside,
and screw the tap to the saddle.

No, that's a tank connector for taking water out of the tank by
gravity, doesn't do what I need at all. I want to connect a pipe
*through* the side of the tank/barrel.

Well use a tank connector or just an ordinary tap connector.

OK, so the cable gland method should do it. CPC has a useful filter for
min/max diameters. One of these should seal to the tank and to the pipe:

Yes, you're right, a cable gland is a reasonable solution, thanks.
