The control knob used to sit at the 12 o'clock position to be off completely. Over time it has headed towards 1 o'clock and now 2 o'clock.

However now it is there it is still not turning off the water completely and I can't move the knob around any further.

My guess/hope is that I need to replace the seal kit. According to my manual that is part no SPSK0014J.

However, that part isn't offered by the Shower warehouse list the shower doc has kindly offered to someone else and I can't find it on google.

Is that seal kit now obsolete? if so what kit should I use?

Given the problems I described above am I well past a seal kit repair and in need of a complete new shower?

Thanks

EDIT:

Further looking found this

According to the caption on the picture the seal kit is an SPSK0043J for serial numbers 18000 onwards. According to my manual it is an 18000 onwards. This serial number would be confirmed inside the control knob, yes?

Hi

Yes you are pretty much on track here is the link to the kit.

You will have seen the other post regarding the Knob.

Hi Doc

I need some more advice on this.

Having sweated on buying the spares for over a year I have now bought them and come to fit them. Rolling Eyes

I have successfully prised off the control knob to reveal a large brass nut with a c shaped ring in front of it and the main spindle that the control knob attaches to coming thru the centre of the brass nut.

I don't know what to take off next. I've tried undoing the large brass nut but it seems stuck fast whichever direction I go in. Obviously I don't want to force it.

The c shaped clip just spins around the spindle.

The manuals only show the exploded diagram of the components and offer no instructions on how to take things off.

Oh and it looks like I will need some silicon grease then?

The Doc · Posted: Mon Oct 19, 2009 9:38 am Post subject:

The Circlip holds the head assembly in place and will need to be removed after the head assembly has been removed from the body.
The large nut can be difficult to remove, it has a left hand thread.

You could try pouring 2 or 3 kettles of boiling hot water over the valve body this may expand the body just enough to help release the head.

Thanks Doc

I did see the LH annotation on my instruction booklet but it didn't register. I actually tried both directions but only moved the entire unit. I'll give the kettle a whirl. I did see you offered that advice on another thread for a slightly different model of shower - the inner workings are much the same.

Have to say that the circlip in the spares kit looks chunkier and sturdier than the thing on there now which actually looks broken at one end.

Yes it may have broken before and it has been replaced with what ever someone had!

Hi

No, I had it fitted from new. I found the other end of it in the bath shortly afterwards! I expect it has just perished. The one in the kit is definitely bigger though.

Whereabouts do I use the silicon grease? Specific parts or on the whole thing?

The Doc · Posted: Tue Oct 27, 2009 2:57 pm Post subject:

The whole thing paying special attention to the threads and ‘O’ rings

Hi,

I moved into a repossessed house two weeks ago and we are having problems with our meynell shower. There was no paperwork on the shower but I believe it was the original one from when the house was built by Bryant homes in 1995. From what I've read it sounds like it could be the Meynell Safemix V6. At first we could not regulate the shower temperature, it would just stay hot, almost too hot too shower but there was no way of making it cold. Two weeks on it now just gets barely luke warm and again we cant change the temperature. There is no problem with hot water in the rest of the house.

Please if anyone can shed any light on this I would really appreciate it, we're bored of having cold showers and just want to find find a solution! Smile

Thanks in advance to anyone that can help!

David

I would suggest a strip down clean lube and fit a new seal kit.

If you are not certain have a look here the V6 and V8 are very similar (The inlet elbows are different)

ok will do, thanks so much for your help. Is this fairly easy to do or would you recommend getting a plumber in? I'm fairy handy but dont want to wreck anything in the process, obviously ill turn the water off first.

Thanks again.

As long as you feel comfortable with turning the water off it shouldn’t be a problem.

Allow yourself plenty of time take lots of photos as you take it to bits, they can be in valuable when rebuilding.

Lay out all the new seals, remove one seal at a time, match it and then replace it

Hi Doc,

Many thanks for your advice to replace the seal kit, clean and lube all the parts but this doesn't seem to have fixed the problem. The bizarre thing is that I succeeded in getting it hot by adjusting the tiny flat head screw that sits inside the unit behind the Meynell badge on the front of the knob. This worked immediately after fitting the new seal kit by turning the screw anti clockwise as far as it would go, but now I am back to square one with no hot water coming through whatsoever.

There is hot water coming through the taps so there is definately still something not right with the shower. Could this mean I need to replace another part?

Thanks & look forward to hearing your thoughts.

The centre screw is for adjusting the temperature however you can over adjust it.

So strip the valve down again and make sure that the small plug http://showerdoc.co.uk/shower-spares/meynell/safemixV6.htm
(The last two ‘A’s’ on the top row) is still in place It could have come out if the valve has been over adjusted.

The 4th a is the adjusting screw slacken that at least two thirds of the way up the housing and make sure that the plug is pushed up against it.

Reassemble the valve and then reset the temperature.

Turn the knob to fully hot and screw the temperature adjusting screw in one turn at a time leaving a few seconds for the temperature to settle after each turn.

Also when the water is off check that the limiters and filters in the inlet elbows are clean and clear. (SPRR0004J)
