.

Your service and communication 10/10.

Bit of a pity but thermovalve is slightly different and I haven't quite got to seeing if I can make it work.

Sorry I should have asked whether you have a solution.

Hi Garry,

Thanks for your kind comment's about our service, however, I'm very disappointed at your review of the actual product.

Nilfisk, the designer and supplier of the product made that item obsolete probably 5 years ago. They are probably the LAST EVER Thermovalves to be available worldwide, and you have to WHINGE, they are different to the valve you have, when you probably bought that machine over 30 years ago, and they changed that valve in the early 90s.

Try getting replacement parts for a vacuum you might go out and buy today.

I call that damned ungrateful. :(

Thanks Shelley,

I'm not sure how much longer they will be available, we've got a few left, most go to New Zealand!
