Waste water pump

[Matt0029]

Hi can anyone recommend a good waste water pump. For clean water so won't need a macerator bit. It's for a waste run that now has 6 meters pipe with a fall of 20mm. So well out of limits for the required fall. Has been tested yet but I don't think will work without a pump.

If it’s really clean water, ie no soap. bits etc, just to move the water - that will do fine.

What size is the pipe and does it rise after the pump before the 6m run with the 20mm fall on it?

 

[Matt0029]

It doesn't rise no. Just a 20mm fall over 6meters. 32mm pipe. Do you think maybe try without a pump?

Where is the waste water coming from, kitchen sink, washing m/c. The height at the start can alter things.

It's a glass panel wash.

It would need a trap on the straight run of waste pipe. Wondered whether they would be enough pressure to force from a hepvo trap horizontally with the lack of fall.

With hepVo traps you loss about 10/20 between inlet and outlet.

The over option is a running trap 75mm seal. Not sure which may offer the least resistance?

There's the mcalpine one that is straight so wouldn't loss any fall on the trap like the hepvo. But sure I read somewhere these aren't to be used on showers. So may not have the force in the water to open it? Thanks

It wont close on vertical.

 

[Matt0029]

Do you mean horizontal?

 

[Matt0029]

That's what it says

It’s more todo with hair keeping the valve / flaps from closing
