Bilge Pump Hose?

[Orla]

I have just removed all the bilge pump hose, could be the original ones possibly around 27 years old.
The old hose is the heavy duty black rubber with a wire which spirals the length.. very similar to exhaust hose.

To replace like for like the local swindlery want around £20/M......i need approx 15m.
I asked for advice in the shop and they reckon it is a bit over the top and most people now use the clear reinforced plastic, much cheaper but in my opinion can kink easily at bends, also is there a likely hood of it crushing under pump use?
So would the white reinforced sanitation hose be a better option, strong enough for vacume heads, should be good for bilges or is there somthing im missing?

Any advice please

It depends a bit on what sort of bilge pump and where it is situated.

For the run from the pump to the outside, almost any hose will do fine. That is under positive pressure so there is no danger of it collapsing.

More care is required if the hose is being used to suck water up more than a couple of feet (i.e the run from the bilge to the pump) but even there a stiff plastic hose should be fine.

Kinking is potentially a problem with any type of hose, and the answer is to make sure that the curves are sufficiently gentle that it doesn't happen

You use plastic cord wound plastic hose of the domestic variety. Cheap and available in many DIY establishments ...

Usually white in colour, with a pronounced spiral ridge of hard plastic cord set into it. Easy to cut apart from that plastic cord. It does not flatten out in curves at all unless crushed or forced.

It's that good - we even use it for additive work and we are using strong pumps.....

Another is the pipe that has crisscrossed fabric set into the clear plastic, but is not so resistant to corner collapse.

There's a green hose that is equivalent to sanitation hose, but is not made from sh*t resistant plastic. Consequently is about 1/3rd the price. Spiral nylon reinforcement.

Have a look at http://www.asap-supplies.com/ where you will find most types of hose you can think of, and a few you hadn't, good prices too. No connection etc.

Local hydraulics shop will have it all at fraction of 'marine' price!

I have 3 bilge pumps:-

#1 is an electric Rule 2000 which is ok with a clear reinforced hose to remove water, as you say under positive pressure.
#2 is a Gusher 30 it needs about 2 meters of hose from bilge to pump.
#3 is a Gusher 10 which is in the cockpit and needs about 6 meters of hose from bilge to pump.

I guess as long as I use a strong reinforced hose of which there seems to be a few to choose from I should be ok.....

Many thanks for everybodys advice
