Bestway Lay Z Spa Siena Airjet Inflatable Hot Tub Slight Leak

Bestway Lay Z Spa Siena AirJet inflatable Hot Tub SLIGHT LEAK. Much loved, unique and rare hot tub. Great design. This is currently being used by us and in working order other than a small leak details as follows: Due to the filter casing becoming stuck on the thread due tightening it too much I had to break it off to remove it. In the process the filter pipe seal (where the filter outlet enters the inside of the tube) became damaged.

I've repaired this using specialist pool adhesive but it's not 100% watertight. There is a very small leak on the outside where the pipe comes through the outside of the tub. The leak is small enough to soak away and I haven't noticed a change in the water level. It may be that a slight top up is required every couple of weeks. The leak has not detracted us from using it and we are still enjoying its use as normal.

Just to confirm pump working fine, heating and airjet all good, tub being used on a daily basis. I have replaced filter housing and comes with drinks shelf. Selling as I intend to purchase a bigger model. The siena model is still retailing upwards of £400. Perhaps someone more savvy than myself could repair this 100%.
