A friend of mine has given me an old hottub. the fibreglass is in great shape,but the pump is shot,and I would like to add a modern digital control panel.Anybody done anything like this and is it worth it or should I just back off this "free gift".
Go to a spa/pool supply place and you can get a new replacement spa pack. Not cheap but cheaper than new spa. I have done two of them and not too hard. Rod
