Great service - excellent quality product.
Wednesday, 1 April 2020  |  Jay

Needed to replace the wet end on my pump as it was dripping excessively and found this after getting a few quotes from professional people that would have hurt my bank balance beyond what I was prepared to pay.
This was pretty simple to fit. I'd recommend taking the pump out completely to change it over, as it's really fiddly getting to the mounting bolts without.
The instructions could do with being a little more detailed. You actually need to remove the faceplate to remove the end from the pump and to install the new one - probably pretty obvious if you know what you're doing, but not to a complete noob like me initially as it looks like you'll be breaking a gasket seal (you don't tho so it's ok!).
I learned loads while doing it and saved myself a couple of hundred quid in the process which is always a bonus.
Delivery was quick, and navigating the site was a breeze.
Thanks

Saved myself over £800 by buying and installing this pump myself rather than going back to original manufacturer. Minor mods to base plate and changed the supply cable from the old one to the replacement only because I had no crimps. Great pump and does the job perfectly...

Do Hot Tubs Need Chemicals

Hot Tub Water: Why Does it Need “Chemical Treatment?”

In the case of a bath tub, you just fill it with water to the warmth you want, take your bath and then let the water drain out. Typically, you don’t bother to treat the water in any way. In the case of hot tubs, however, you have to take the trouble of treating the water with different chemicals. Why this difference?

A hot tub typically accommodates more than one person at a time. It is more a place to relax for longer periods rather than just take a quick bath. Often, it is used for therapeutic purposes, to get relief from aches and pains through a hot soak and a therapeutic massage provided by the jets built into the hot tub.
