Bath Shower Mixer Tap Problems

[timmydog-1977]

Hi all, please can you help with this problem:

My original bath shower mixer tap was 12yrs old and developed a problem so I thought I would buy a whole new similar style unit. I fitted the new taps and all was ok for a week or two. Then i noticed the hot tap would only turn two full turns but before it would turn three full turns. Over the next few days this got worse until I could no longer turn the tap at all.. I took them back to B&Q and got them exchanged for identical set. Again after about a week, the same thing happened. I have now replaced them with yet another set and the same thing is happening again. The funny thing is, when i remove the taps to take back to the shop, the problem goes away and they turn as they should, so im thinking its something to do with the water pressure?. I dont think I have unusual amount of pressure at my home and no other taps have broken in the house in 12yrs.
Hot water is fed by a combi boiler so I thought it maybe because of this but the cold water tap also develops this problem after a few weeks of use.
Please see the link below for these taps.
Any help is appreciated..Cheers

the taps are for low pressure you have high pressure i.e combi you need suitable taps for high pressure

Hi Steve, thanks for your response.
I thought low pressure taps can be used on either low pressure or high pressure systems, but high pressure taps can be used only on high pressure systems.
The taps I purchased are suitable from 0.2bar upwards but they dont state a maximum pressure. ?

Have just had the same problem with a customers tap, put it on in August, been replaced once already. Ive just taken it back for a refund. Personnally i dont think pressure has anything to do with it, these are standard mixer taps and shouldnt have any issues in a normal house with a normal combi boiler system. I suspect Plumbsure has had a faulty batch, wouldn't be surprised if quite a few more have been returned.
Take it back and go for a refund, for your info my customer is getting an almost identical set from Focus, similar money
