The great impeller scam.

Do you know what an impeller is?

[billgewater]

To "impel" presumably means to "force" momentarily. I suspect the agents who sell these items believe the word applies to the price ... as in momentarily push up the price.
Or maybe it just falls into the category of "Oh! You own a boat! What else would you expect?"
As impellers have "vanes" then maybe "vanity" arises. Vanity is often associated with high prices in the fashion world and what's more fashionable than a toilet macerator eh? Produce one from your man bag at your next dinning out event. Total one up-man-ship!
Further on "vanity", we all know that if you don't take our impellers for a "spin" they will start shedding bits and become cantankerous.
Or maybe each impeller is hand made in a small workshop in the Bavarian forests by highly skilled traditional craftsmen with a long list of academic and trade qualifications and secret knowledge.

Otherwise I have no real explanations.

RE the advice: If your overboard discharge system needs a pump, ditch your macerator type and replace it with a diaphragm type. You won't need to revisit the issue gain. Macerator pumps can't be run dry, diaphragm pumps can. Macerator pumps have metal blades that rust, foul, and break. Diaphragm pumps don't rust or foul, and the rubber diaphragms last upwards of 15 years..."

I totally disagree. these diaphragm pumps are liquid-only with small I/O hoses, totally unsuitable for waste management. I am a proud owner of 2: 1980 vintage, personally- rebuilt par - jabsco diaphragm pumps. the inlet and outlet hose sizes cannot possibly accomodate the solid items typically put into, chopped up, then and macerated out of a macerator pump . new par jabsco diaphragm pumps start at about $350 each, compared to $100 macerators.

Disagree all you want, diaphram pumps, both electric and manual, have been used for waste, both black and grey, for many years. Google diaphram waste pumps.

Those specific diaphragm pumps wouldn't work, but several companies make bigger ones with 1.5 inch I/O ports and a big single diaphragm chamber specifically meant for pumping waste.

The replacement cost of those parts in full carbon ceramic is $32,206.74.

The pump costs $250 and the impeller 10% of that.

Seems ok to me.

That's my macerator pump. I've replaced the impeller perhaps twice in 12 years, and both times due to my own stupidity attempting to pump out with the discharge sea cock closed. I can't say that I can complain.


Another matter is the dissolving screws. But Jabsco issued an upgrade at reasonable cost to deal with that, which I duly did.

They only deliver to Canada or the USA and the price is

Only €20 from SVB.24

https://www.svb24.com/en/impeller-ni...s-type-1_.html

They deliver all over the world.

Similar price from ASAP Supplies in the UK.

Seriously, you need to shop around more. Googling the part numbers will open up whole new horizons for you.

Labor to replace the battery on Land Rover is $525. Takes 10 minutes. No DIY as you don't have the proprietary software to reset the system.

I wish my brake pads only cost $300 for just the fronts and I have always serviced my own brakes. My Nissan costs about $1200 a year in brakes.

Well, you're in Thailand, right? What do you expect? I guess the next thread will be "Shipping to Remote Places Scam".



Did you just move there? People I know in such places save up their orders into one big one to save on shipping, even going in with other people. I'm sure 10 of these would be the same shipping price, which is already only €4.80 per. Alternatively, have someone flying in to bring in their baggage.
