threewheels Posted March 4, 2021 Share Posted March 4, 2021 Hi Everyone.....We are new to all this, when i went to check the motorhome shower, the hose which was disconnected i thought for the winter set up, as in no water in anything etc ,when i went to attach the shower hose to make sure everything is working before setting off the hose doesn't fit the tap, i have since been told it should be 3/8 x 1/2 inch fittings 1/2 for the shower head and 3/8 for the tap, where is the best place to buy either an adaptor or a short shower hose with the correct fittings these 3/8,1/2 bsp sizes are just what i was told is there any other fittings i need to know about thx in advance for any help cheers Chris and Caryl Link to comment Share on other sites More sharing options...
Derek Uzzell Posted March 4, 2021 Share Posted March 4, 2021 You really need to be more specific regarding the model of Miller motorhome you own and its age. https://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/shower-tap-threads/57693/#M683851 Motorhome/caravan shower hoses may have 1/2” - 3/8” end fittings or 1/2” - 1/2” end fittings. (example advert for both types here) https://www.leisureoutlet.com/caravans-and-motorhomes/water-and-waste/taps-and-shower-fittings/9173-reich-shower-hose--12 I don’t know which type is the most common, but a GOOGLE-search on “caravan shower hose” should identify plenty of potential suppliers. (For example) https://www.caravan-components.co.uk/Caravan-Shower-Hose-15m-Chrome-1/2-x-3/8-only https://www.caravan-components.co.uk/Shower-Hose-15mt-in-Chrome-1/2-x-1/2-Fitting (Not easy to respond to your enquiry without knowing what the ‘tap’ looks like...)

ColinM50 Posted March 4, 2021 Share Posted March 4, 2021 Personally if it were mine, I'd wander into B&Q and try different fittings. Find an older bloke in there, explain your problem,. and ask if you can just try a few leaving a hefty deposit. Link to comment Share on other sites More sharing options...
Keithl Posted March 4, 2021 Share Posted March 4, 2021 I replied to your earlier thread then found you had started a new thread so have moved your previous post off the forums. Please only post one thread relevant a particular problem/question as otherwise answers get disjointed and lost. If you want a title or content editing add a post addressed to the mods and we will oblige. Keithl - 2021-03-04 4:50 PM Unfortunately not a make and model I'm familiar with! Seeing as one sold recently near Southampton would this be a recent purchase? If yes then return to the dealer and ask them to supply the correct shower hose. If no then take what you have to either a B&Q style store or a bathroom specialist and see if they can help. https://www.meadensofhythe.co.uk/datasheet/dealer/8756/stock/859/ Keith.

Alanb Posted March 4, 2021 Share Posted March 4, 2021 It may be helpful to note the following rough guide to common BSP thread sizes, which are also ISO standard. The nominal size relates to the bore of a steel, water or gas pipe. Allow a nominal 1/8" for the wall thickness of the notional pipe. Hence 3/8" BSP will be approximately 5/8" over the thread. Likewise 1/2" BSP will be about 3/4" over the thread. More exact information will be revealed by a web search. Alan Link to comment Share on other sites More sharing options...
colin Posted March 4, 2021 Share Posted March 4, 2021 I doubt this will be a specific motorhome part, I would imagine the original hose failed and someone brought a standard household hose which doesn't fit. You either need to buy the correct hose, or a adaptor off eBay. My concern would be that the original might have been metric and not BSP. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted March 5, 2021 Share Posted March 5, 2021 If I bought a secondhand motorhome and found that its shower hose was present but had been disconnected from the shower’s mixer-tap (as Chris has said, possibly to guard against frost damage) I would assume that the hose is the correct one for the tap. So, if one end of the hose would not connect to the tap, I’d try the other end. As will be evident from the following link there is a host of shower mixer taps marketed for motorhomes/caravans https://tinyurl.com/px7v3xh9 and these generally have a 1/2” BSP outlet. There are taps with a 3/8” BSP outlet (examples here) https://www.leisureshopdirect.com/water/caravan-taps/caravan-tap/shower-tap-with-3-8inch-bsp-outlet https://www.caravan-components.co.uk/Gold-3/8-Outlet-Single-Lever-Caravan-Mini-Mixer-Tap so - although those taps seem to be in the minority - Miller may have been fitting them as standard in 2009. (To the best of my knowledge , the outlet will always be either 1/2” BSP or 3/8” BSP.) As colin has advised, it is possible to obtain male-to-female adapters so that a shower-hose with a 3/8” BSP end fitting could be connected to a mixer tap with a 1/2” BSP outlet (or vice versa - 1/2” hose to 3/8” outlet) but it’s not an attractive approach and probably just as cheap to buy a new hose. However (as Keithl has said) if the vendor of the Miller motorhome has sold the vehicle with an unusable shower, it should be the vendor’s responsibility to put the matter right.

You either need to buy the correct hose, or a adaptor off eBay. My concern would be that the original might have been metric and not BSP. While confirmation would be sensible, it should be BSP, as this is the ISO standard for pipe threads. Alan Link to comment Share on other sites More sharing options...

One of my 'earners' is making SP adaptors. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted March 5, 2021 Share Posted March 5, 2021 This link https://www.notjusttaps.co.uk/understanding-bsp-sizes.html should allow the mixer-tap’s outlet size to be identified. Within this 2018 UKCampSite forum discussion the possibility that a shower outlet might be metric was raised. https://www.ukcampsite.co.uk/chatter/display_topic_threads.asp?ForumID=12&TopicID=350865&PagePosition=1&ThreadPage=1&ReturnPage=Search&search=&searchIn= But (as I opined above) the outlet of the shower mixer-tap originally installed in a 2009 Miller motorhome will most likely (say 99% likely) be either 1/2” BSP or 3/8” BSP. Consequently, if a shower hose end-fitting is loose on the outlet it means that the outlet is 3/8” BSP and the hose connecter is 1/2” BSP, or if a shower hose end-fitting is plainly too small to screw on to the outlet it means that the outlet is 1/2” BSP and the hose connecter is 3/8” BSP. It’s perhaps worth adding that the threaded male inlet of a shower-head may also be either 1/2” BSP or 3/8” BSP, meaning that - besides the shower hose needing to have the correct end fitting to connect to the shower tap’s outlet - the other end of the hose must have the correct end fitting to connect to the shower-head.

Derek Uzzell Posted March 16, 2021 Share Posted March 16, 2021 Chris and Caryl Did you manage to resolve the peculiar problem with your Miller motorhome’s shower hose? If so, what was the verdict, please? Link to comment Share on other sites More sharing options...

threewheels Posted April 2, 2021 Author Share Posted April 2, 2021 it was simple as finding the hose with the 3/8 bsp on the tap end, 1/2 bsp on the shower head end just needed a different hose but i didn't know this was available when i asked the question, thx for the help the forum made it easier to get sorted cheers chris and caryl Link to comment Share on other sites More sharing options...
