Most reliable macerator?

[very_pointy_ears]

Having done a search on "saniflow" in this forum it seems that most people have little regard for them. Is there a better make?

I'm going to be putting in an en-suite at the front of the house on the 1st floor. All plumbing is at the back, about 7 metres away. The pipes are going to have to run in the floor void and so there's no chance of much of a drop.

Also, I want to have a shower. However, I have long hair and some of it is going to go down the plug hole. Is this a recipe for disaster?

Lets just say I would prefer to dig the lounge up and extend the drain.

Why I don't like sticking my arm in a bucket of 4x

If you've ever had a waste disposal unit in the kitchen sink, these thing work the same only a tad stronger.

Digging up the lounge sounds horribly disruptive. What is the typical cost for doing something like that?

Saniflo's a good make, but nature of the beast - these contraptions are noisy and if they go wrong...not pleasant and can be expensive to fix, unless you don't mind dealing with macerated Mr Hankey

Still having the nightmares about them , but they do work for some people...absolute last resort though!

It'd cost a fair bit to run 6" soil pipe, but depends on the job...hence mods intervention Call someone in to give a quote.

Thanks for your replies.

If it turns out I have to resort to a Saniflow anyway, maybe it's worth me considering just using one for the loo and having the washbasin and shower on a seperate pipe, not going via the Saniflow. At least that reduces the risk of hair getting in and clogging up the macerator. Also, it will solve the problem of getting a drop from the shower tray into the Saniflow - something I was not clear about anyway.

Because of the room layout, the shower drain will be shorter - say 4.5 metres. If I fit a slightly wider pipe (eg 2 inches), would this be sufficient on its own with a very shallow drop? Basically, the max drop will only be about 5 inches over that length because that'll be the amount of free vertical movement a 2 inch pipe can have in a 7 inch floor void.

It's going to be a pumped shower so there will be a reasonable flow.

Live long and prosper

I'll do my best

Putting a 50mm waste on a short-ish run from a shower will not make much difference to the actual flow - especially given you'll get a slightly better fall from a 40mm waste. But the advantage of a 50mm is that there's much less chance of a blockage under the floor. If it's a straight run AND you can put a rodding access on the end of it, I'd use 40mm. But then again - the rules say 50mm over 4 metres - IIRC.
