TMC Electric Toilet Pump - Anyone Familiar with these ?

[charliehows]

I recently finished installing a TMC electric pump with macerator - Ive found that i have to manually add water into the bowl and wait a while before it can handle toilet paper in anything but the tiniest amounts - anyone use this sort of unit got any tips?

[peghall]

TMC toilets aren't very good toilets, but they're not THAT bad...so I suspect either a defective toilet or an installation error. Did you get any kind of installation instructions with it? I spent about 30 minutes googling for TMC electric toilet instructions, manuals and every other search term I could think of, but couldn't come up with one.

So my advice: talk to the vendor or distributor who sold it to you...if they can't help you, they may be able to refer you to a yard customer who can.

Wish I could be more help!

i have fitted tmc as well and they don't have any info on installation but if you call the shop they actually have (behind the counter ) several different sketches of how it is all supposed to be installed at leaast Whitworths did (i dont know why they dont just give them out at purchase time) with my pump being installed below waterline i needed some 'antisiphon valves' to prevent the water overfilling the toilet pan.
they are very "experimental" in the approach to fitting all boat needs (you need to do the exercises) . i also seem to recall that someone had sketches in their booklets but i cant find any at the momement

I had no issues with mine, over 5 years of sometimes brutal use and they have gone in many boats I have been on also with no issue.
I always turned ballvalve on before use, letting water into the bowl.
Installation is easy, pretty much the same as any other 12v marine toilet.

Have had a TMC instaled now for three years, works a treat. Because they are so cheap I bought a backup TMC so I don't get caught with "my pants down". Nothing worse than being miles from knowhere without a service-able loo.

Hey Australis: check out the thread about the French...apparently one of our members here has observed that it does not seem to bother the French too much not having a servicable loo, or a loo at all Imagine the savings in initial costs and grotty maintenance.

It may be worthwhile to check the voltage at the pump when in use. Voltage drop could cause underperformance.

thanks for the responses - overall i'm happy with the functioning of the thing, it seems in my case it just has to be treated with care.

"TMC toilets aren't very good toilets, but they're not THAT bad.."
Peggy I'm shocked!!! TMC toilets look like bad knockoffs of the Jabsco toilet you hate so much. Coming from you, that statement was high praise. (just teasing!)

[Wanderlust]

I replaced my aged Jabsco manual with a TMC electric to please the Admiral. Apart from mounting holes it was a straight replacement. The bowl fills easily and pumps fine.

Try disconnecting your hose at the pump inlet and check that water flows well (could be a partly blocked intake at the hull). Is it sucking air at the vented loop and not priming? Not sure what you mean by " .....wait a while before it can handle toilet paper".

[peghall]

A Jabsco is high quality compared to a TMC! I only meant that they usually work at least a LITTLE better than Charlie's seems to, right out of the box anyway.

Happy Thanksgiving!

I wouldnt have one of the standard TMC's, even though I had no problems with mine.

I will be having one of the more luxurious models though
At $399 they are a bargain
TMC Luxury 12V Toilet

I can have one in each hull for the cost of a single Jabsco, which is probably of no better quality apart from an expensive name.

I installed two Raritan Atlantis toilets 7 years ago and had zero maintenance since... I mean not even a joker valve !

My old toilets would have required so many rebuild kits that it would have cost more..

I can only come up with one explanation: fresh water flush instead of raw water.

ciao!

I dont get this extra cost required for fresh water flush.
Isnt it simply a matter of connecting the inlet to the fresh water toilet supply tank instead of seawater inlet? Hey presto, cheaper salt water toilet is now fresh water.

And better still, why not have a Y valve for inlet allowing choice of fresh flush or salt for times when fresh may be at a premium?

And aren't all the parts in contact with the water plastic and rubber anyway, would salt water have any affect?

[s/v Jedi]

For fresh water, you're gonna need a solenoid valve to stop that pressurized water. Also, the Atlantis has a vented 1-way valve to make sure that your fresh water can't be contaminated by the toilet.

The fresh water keeps all the plastic and rubber parts in good condition, while raw water has got them scaled over quickly.
