Heads hose!

[goochie]

Just spent the whole day on the boat dismantling and unblocking the heads. Oh joy! Daughter no.1 forgot to give one of her friends the lecture on toilet etiquette when they were staying on it a couple of weeks ago. Anyway, I had to remove the hose from the toilet to the diverter valve on the holding tank as the whole system was bunged up with blooming FlashWipes all the way back to the valve. Problem is I had to sort of destroy the old hose to get it off. Very solid s/s wire re-inforced bit of Beneteau original kit. No probs thinks I, I'll just pop to swindlery and get new hose. So that is what I do, and return armed with enough spares to build a new toilet, and 2 meters of their finest white 38mm sanitary pumpout hose.

Problem no.1 - hose will NOT go onto fitting on diverter valve thingy. I got it on the toilet discharge elbow end no probs. I've tried heating it with boiling water and all the usual tricks, but it aint going to go. Apart from anything else one of the problems is of course that I'm working in a space the size of one of Ronnie Corbetts shoe boxes.

Anyone know were I can get something like 42mm hose of the right spec. or any other ideas about how to get the sodding thing on? It's really starting to tee me off. For what it's worth, I'm not sure the original Benny spec would be much easier knowing how much I had to abuse it to get it off.

Had the same problem on our Sealine. First hose came from Marine Superstore in PS. Couldn't get it to fit. Went to the Percy Lee Chandlers in Fareham looking for inspiration and found there 38mm hose from a different supplier. Hot water trick worked first time and it just slid on.

Boiling water then use a large tapered wooden plug to open up the hose.

Thanks, I'll give them a try.

I think I'll have to try a different brand, as I tried opening up the hose, but it still wasn't playing ball. Maybe a different hose will be better. Thanks for suggestions anyway.

I presume you're using some lube and have taken off the easy end. The wire should be spiralled, so if you twist the hose clock-wise as you push it on it should slightly open the hose and hopefully be easier to push on. Obviously twisting the other way will cause it to tighten. Also you could carefully use a very sharp knife and chamfer the inside of the hose.

Thanks. Yes, I did lube the hose with vaseline. I'm presuming this should be OK with the plastic material being used. The main problem is not just getting the end on - I've managed to do that by using all the methods described above - it's getting it far enough on the fitting to accomodate two hose clips and for me to be really comfortable that it's going to stay on. I'm going to order a different brand of hose, and give it another go.

Why not adress the problem from the other direction: -
Hose too small = diverter valve too big; I'm assuming that the hose stub on it is ribbed? In which case, in addition to stretching/lubricating/heating the hose, file down the ribs on the diverter valve - this worked for me when I'd the same problemfitting an inaccessible holding tank hose

 

[goochie]

Hmm. That's worth a shot. Just got to find a friendly leprechaun to do it for me - it's really tight in there!

Use a heat gun to get the hose good and hot. The trouble I found with using boiling water was that the hose cooled down so quickly that I didn't have time to get it into position to get it on. Heat gun worked a treat.

aha! Now that I will try.

Ditto. It needs a lot of heat.

Heads hose! - it worked

Had the same issue, had tried hot water, WD40, some filing, lots of brute force, some swearing and looking for another type of (softer) hose.
Just searched the forums and found this advice... and it works. A combination of some heat from a hear dryer and twisting in the opposite direction to the coil of the hose reinforcement made it slip on much more easily than I ever believed possible.
The problem was not actually the hose or other fittings at the specified 38mm but just the Y Valve (YM Yachting YT-460) which said it was 1 1/2 inch but was a little over 40mm, i.e. 2mm oversize.
Thanks!

Got the same issue on our boat, Jeanneau Prestige 36, the fitted (French) hose is 40mm id,
the UK standard is 38mm, Have scoured Plymouth trying to find 40mm to no avail. Gave up and instructed Mountbatten Boathouse to sort it.
