Will set it out and take some pics to post on my build page to see what people think and changes that might be needed before I plumb anything in. How come the slide valves seem to break so easily surely they should be designed for the use of opening and closing

here is the manual page and I copied and pasted this bit. http://absolute-koi.com/pdf/UltraSieveIII.pdf
Make sure the UltraSieve is on an equal, level, underground. The upper edge of the UltraSieve must be 1 cm above the maximum water level. Between the bottom drain and the UltraSieve we strongly advise you to use a slide valve to separate the UltraSieve from the pond when necessary. The inlet of the UltraSieve is made of 110mm Polypropylene pipe so you can use a PVC push fit fitting. Since the UltraSieve is made of Polypropylene you cannot make glue connections. The UltraSieve has 2 inlets of 110 mm of which one is closed. If you want to use both inlets you have to cut off the end of the closed one. Note: Do not install the UltraSieve directly in the soil! Make sure there is always enough room around the unit. When there is pressure on the unit it will not work properly.

i only have one inlet being used on inlets on ultra sieve 3 , so i used a rubber boot stopper on the other 4 inch inlet one of these Flexible Rubber Boots - Pipework & Fittings - Absolute Koi
if you look in manual section on The auto-adjustable dam with floating device
this is where you set it up for your pump size( important ) to give you an idea my pump is a 8000 liter pump and its in the middle slots
you can run your pump dry or overflow if you get this wrong. i know i have done itLast edited by freddyboy; 05-03-2019 at 05:25 PM.

probably because I don t know my own strength haha. seriously . maybe I got a weaker handle then most. it was the discharge on the sieve to waste. which comes attatched to the sieve, it was a brand new
sieve as well. the handle lasted six months, had it over 3 years now. still working, but as I said with tie raps haha.

How do you fit.new seals if you take the valve off wouldn't the pond drain? Sorry if that's a stupid question I just don't understand how it works

I did a mod on here a while back to stop slide valves leaking.
Basically if you take the four nuts off there are two seals one each side of the slice,make a backing washer to fit behind ONE seal,I tried two but it was too tight,I used a thin piece of plastic behind one washer to make the seal work more,worked for me.John
