So the cartridge filter to a sand filter system had to be replaced. Since we did not want to spend all too much money, we have put ourselves on searching and finally decided on the Speed Clean.
The structure was inadequate despite manual relatively easy and took about 1 hour.
As we have already read a lot in advance that it is difficult to block the pump tightly.
We have insulated with Teflon tape neatly from the very beginning all the connections. Thus, the pump was really tight from first operation.
The instructions can but unfortunately to be desired. For example landetet the first backwash the pool.
Since the inlet and outlet of the valve are not labeled and let the images on the display to make a wish.
So my wife has read the manual and I assembled the pump in the process try.
There are not many parts to assemble, the assembly is partly self-explanatory. However, there are several ports on the valve and this could be labeled.
In operation, the system runs quietly and done decent job.
