Triton combi cartridge swap

[Darren553]

Hi all,

i have fitted a new shower pump to power 3 Triton LP showers . I have swapped the 3 LP cartridges to HP cartridges but they all leak badly. I have measured the width of the old and new and they are exactly the same but top to bottom the new HP cartridge is 4mm smaller so the O rings don't seal !!

Any ideas ?

Cheers Darren

Give triton a call, I wouldnt change a cartridge for a different one unless i knew for sure it would work. the housings must be different for it to leak badly.

You need three sets of these.

Triton Retro Kit Biv 86000680 | Triton | Shower Spares | Shower Doctor

Hope that helps.

The customer has supplied the cartridges and apparently they have spoke to technical and were assured these were the correct ones . My job was just to fit the pump but I said I would replace the cartridges for them as they only take 10 mins each to swap (wish I hadn't of bothered). I was just wondering if anyone else has had this problem ?

Cheers shower engineer - does that retro kit make up the 4mm difference ??

When the HP/LP range were originally brought out the carts were identical in size. Triton soon found out that above about 4 Bar the HP carts were not up to the job and a redesign beefed them up. This also reduced the dimensions on the two outlet ports so they produced the retro kit to convert from the old style to the new style. Although not designed for the purpose of going from LP to HP they do exactly the same job.

Hope that helps.

Thanks mate I will get the customer to order them and this time charge them to refit.

Hi just a quick update , the customer has spoken to triton and they no longer do the retro kits for the exposed valves - only the concealed valves, so he has had to buy the complete units including HP cartridges.......
Expensive.

May be too late for you now but I think you can still use the adapters. The old style adapter had a slightly longer stem and two grooves for the 'O' ring. The reason for this is that the valves were supplied with an outlet adapter, basically a 15mm x 1/2" MI compression fitting. For concealed fitting you would use the MI end screwed into the body and the compression end would go to the outlet elbow. For surface mounted installations the fitting was reversed so that the flat end of the MI fitting allowed the shower hose to screw on nicely with the beveled edge of the comp fitting inside the valve body.

The retro kit I linked to is for the built in valve (BIV) and if you use it as it is then it will leak as the 'O' ring will try and seal on the beveled edge. All you need to do is take the fitting out and reverse it and it will be fine, you then have to get the shower hose to seal on the beveled edge, not ideal but a lot cheaper!

For anyone subsequently reading this who wants to try it I should point out that I haven't fitted one of these for several years and it MAY have changed so check first!!!

Hope that helps.

I did think it would be able to be used somehow but the customer is dealing with it all so i'm trying not to get to involved - just asking on here as i knew i would receive excellent advice.
Thanks again shower engineer i will report back on here when the whole lot turns up and its fitted.
