One of my bottom drains returns to a midi sieve. It’s never been an issue from when it was installed. For the last couple of weeks though the sieve side has started to fill with water, it’s to about half depth of the weir side which is obviously stopping it working as it should. Does anyone know what adjustments I need to make to rectify this please?
1. have you changed the flow rates from the sieve
2. if you have, you may have to adjust the flow rate control. (my U/S 3 has 3 setting for different flow rates, look at U/S instructions how to do this)
3. if non of the above - remove the float - bit of a hassle - empty all of the water out of the float and refill to correct amount. (the float plug could have become loose and allowed water to fill it)
Let me know have you get on.(don't forget some good isolations if required)
