The check valve and the filter basket can be removed and I have cut off the bottom port because it does not fit in my beat well pipe. However, the check valve could also be used at the other end, since the same 33.3 mm port was used, good solution. Again, it worked reliably and held the water column constant hose.
The tube was sealed and immediately wrote also good against the Gardena pump connection pieces from the inner seal fulfills its purpose.
I can only suggest rather spend a little more money, because the cheap hoses kept with me through a summer. Gardena uses the much stabiliere and high-quality looking material here.
