Hi Marcc,
If you are in the USA please give http://www.autopot-usa.com a call they will be able to assist you, as we are based in the UK. Are you using the new AQUAvalve 5 in the old tray design as the new AQUAvalves should only be used in the new grommeted trays…. But speak to the chaps in the US, I’m sure they will be able to help
