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.

 

[Matt0029]

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

 

[Matt0029]

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

 

[Matt0029]

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

 

[ShaunCorbs]

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

Wasnt the McAlpine valve I had in mind- sorry.

 

[Matt0029]

May try the mcalpine one. I could use a running trap but I think the machine is only emptyied every week or 2. So not sure if evaporation will be a problem.

 

[Ben-gee]

It won’t evaporate in 2 weeks, unless a heat source is right there o suppose

 

[rpm]

It might if in Canada right now. Haha

Too true!
Mind you Matt0029 in Leeds, more likely to re-fill the trap with drizzle than evaporate it with heat!
