I'm using some of this hose: http://is.gd/8XVzq for a bilge pump on my
boat. The name kind of implies it would be suitable, don't you think?
However, despite the pump being one of the most common in the country,
the hose won't seal onto it because the jubilee clip only pushes down on
the spiral reinforcement and water is able to track down along the
material in between. I don't want to change the hose because other than
this problem it's quite suitable, and the other end is already installed
in a difficult-to-access location.

I've tried packing the gap between the spirals with cord so that the
jubilee clip would be pressing evenly everywhere, but it didn't make
much difference. I've thought about adding some kind of sealant to the
joint but it seems like it would be pushed off the nipple ahead of the
hose when I slide it on.

The pump is over what will become my bunk once I get time to build it,
so it needs to be drip-free. Any ideas?

Cheers,

Pete

How about cable ties in the valleys?

hmm, ignore this ... as it looks like the hose is really spiralled and
not ridged.

To be honest I would think that the hose is the wrong internal
diameter as it should be that this hose can be expanded by twisting
against the spiral and should then already be a tight fit on the pump.

Mark

How abouts stripping the coil out of a short length of hose and laying
this in the valleys and clamping with a jubilee?

how about "wiping" silicone to fill the internal "valleys" of the
spiral (as far as necess to suit the pump), leave to cure then jubilee
clip?
assuming its the output of the pump this is connected to what would be
the issue with "plenty" of silicone?

cheers

Hi Pete

Does it actually matter that it drips?

You are emptying an amount of bilge water out and any that leaks simply
returns to the bilge to be pumped later anyway doesn't it? Or is the
pump away from the bilge in which case I can't help ;-)

A wire hose clip would probably do the job. Like this but you might get

Hmm, might be worth a try. It's not spiralled though, so there'll
probably still be a gap.

That's right.

diameter as it should be that this hose can be expanded by twisting

Well, it does need to be twisted open to get it onto the nipple, so it's
a fairly tight fit, but not tight enough in the valleys to seal. I took
a piece of the same hose off a bronze nipple (the problem one is
plastic) and could see a thin spiral mark of discolouration where the
water had been seeping through.

That's the idea I was aiming for with the cord. The problem is that
you're still left with a spiral channel between the old reinforcement
and the new.

The inside of the pipe is basically smooth when it's not connected.
There aren't valleys as such, just areas not under pressure from the
clip, through which a tiny trickle of water can leak and then drip.

the issue with "plenty" of silicone?

It's connected to both sides, but I'm trying to fix the problem just on
the output until I find something that works. The reason I don't want to
gob silicone over the outside is simply that it rarely works - silicone
needs to be in between two surfaces to seal them. I don't think I can
achieve that here because the pipe is a pretty tight fit and will
probably wipe it all off as the pipe goes on.

Thanks - they don't look like a retail supplier but I've pinged them an
email to either suggest where I can buy some or sort out a small order.
