• Please tell me where to buy a screw plastic drain valve.

Good afternoon! Could you please tell me where I can buy a threaded (fine-tuning) plastic valve for draining seawater from the display into the sump? Preferably worldwide (with shipping to Poland - both expensive and slow). The valve is needed for a pipe diameter from 25mm to 45mm... Thank you in advance.

I will provide the link later.

We probably see different information on the website... I get a list of many faucets, but they are all quarter-turn (ball) and not screw-type. There is one screw-type faucet, but they only sell it wholesale from 500 pieces.

I use a ball type. I will try to find a screw type.

I'm currently using a ball valve as well, but from time to time it needs adjustment, and it's difficult to do because the valve is stiff, making fine tuning impossible, resulting in either too much or too little... I searched and searched on AliExpress for a screw valve, but so far I haven't found anything other than the one sold in bulk...

It looks like a screw, but with copper inside...

You won't adjust it every day; the voltage in the network changes, and the overflow has inertia. Set the level at the overflow with a margin, and there will be no noise when the return drops.

That is, to increase the length of the pipe between the water drain hole and the top of the pipe? It starts to gurgle in two scenarios - when the water level drops to the bottom part, where the water "enters the pipe," or when the level is too high and the water reaches the top of the pipe all the way to the end.

Do you have an air valve? If so, it can regulate the flow "more finely" than a ball valve.

Beth3383

No, the air valve is not necessary. I read that it seems you don't need to install it on the drain "Stokman"...

Gregory

Still, practice shows that a fine adjustment valve on the drain is necessary. I found such a valve in Poland, but it is quite expensive (about 1800). Maybe someone has seen something similar, but cheaper - somewhere with the Chinese...

Andrew9581

It's not much cheaper here.

I adjust.
