Multiple Flush Requirement in Compact Toilet: Drain Pipe Maintenance Queries

Question

Hello. I have a problem with flushing in a compact toilet, i.e. I need to flush several times to remove impurities. An apartment in a block of flats on the 2nd floor, recently renovated where the drain pipes were cleaned. Please give me hints where I can look for the problem.

brofran · Answer

Well, it looks from the video that they cleaned it well, because the water flows into the sewage system without resistance. The reason for poor flushing may be the design of the compact itself. In my opinion, those with a swirl flow of H2O are the best to rinse.

And does the fact that the outflow is horizontal does not affect the flushing, should it not be lower than that in the compact?

Romulus7874 · Answer

By this reduction, you simply have a slightly higher water level in the siphon. This slows down the flow a bit. The design of the compact itself also has an impact; You never know when buying. You can't check it in the store, and after assembly it's already after the photos

brofran · Answer

If it is a short section, e.g. 0.5 m, it does not interfere with drainage from the shell.

So nothing can be improved to make it work better and the only thing left is to replace the compact?

I do not understand this reduction (black) at the exit of the compact, I have several seats in the house, the distances from the vertical (max 0.4 m) are different, but the diameters of the pipes at the exit from the compacts without any reducers and niagara, the first I see such a solution once, I think it will be possible to replace it with ordinary plastic sewage fittings.

I don't see a problem with the drain plug. You have a lousy flush jet. Raise the water level in the tank to the maximum, and if the overflow does not allow, then install another valve with a higher column so that the water level drops from the very top, not from the middle of the cistern.

Water height in tank = hydrostatic pressure, higher pressure = higher flow.

lisu24 · Answer

The water level is set to maximum, practically the entire tank is filled, I think the problem may be that 80% of the water is flowing from the side of the tank and it should flow around the entire shell.

If the flush starts from a full tank, the only problem is the valve that throttles the flow for some reason. Is it incorrectly assembled, clogged, damaged, does not fully open, etc. Possibly a blocked channel in the bowl.

From what I can see in the video, too little water is flowing there, the compacts are so that they rinse with a minimum amount of water. I used to have a compact and I threw it away in favor of a toilet with a separate flush. For several years, there was never a time when she couldn't flush something.

Hello.

In the video you can clearly see the rising water level in the bowl. In my opinion, the cross-section of this reducer is too small or, for example, a basket fell in and no one reported

. I know from the autopsy - there are no guilty parties. After pulling out the culprit - aaaa ... because I was disgusted to take it out. Life itself.

sztajger · Answer

Hello. I confirm the observations of my predecessors. Water - as you can see in the video, it flies... no! It flows too lazily, so the current will not carry the solid particles with it ... in addition, the connector has a strong narrowing, which also causes slow transport of the removed matter ... and manifests itself by raising the water level in the siphon.
For many years I struggled with poor flushing in the toilet - a weak stream from the cistern and, as it turned out, a calcified siphon / drain. Finally, I replaced the old toilet set with a compact one, which (although it has a shelf) works without major problems.

Did nothing fall between the cistern drain and the toilet bowl? My children once threw a small rubber toy down the toilet and it blocked the water channels in the bowl. After removing everything ok.

lisu24 · Answer

Nothing fell into the bowl, the compact is new, so I wouldn't look for a problem in the calcification either. Is there any way to improve the water drain, the drain valve should be set in a special way?

cirrostrato · Answer

Once again: I would first remove this restrictor in the drain (low cost but you probably have to unscrew the compact from the floor at a glance) but if you don't want to listen to such advice......

lisu24 · Answer

It's not that I don't want to listen to advice, but I would like to start with what is the least invasive, and this drain is really weak compared to what I have observed in other toilets.

cirrostrato · Answer

Well, combine, theoretically, further ... I have four seats (different types, not purchased at the same time) in the house, large cross-sections go immediately from the exit (ordinary plastic sewage fittings), in one immediately down at the bottom of the compact, in the second / third exit from the back (like yours) and immediately a 90-degree bend down, in the fourth (basement) a 90-degree bend immediately to the left and with a slight downward slope to the vertical half a meter further, no problems for years, even after a lavish dinner. Good luck with your work, regards.

Romulus7874 · Answer

I would look at the drain valve itself. Looks like some cheap plastic. Does it have any regulation?

lisu24 · Answer

This is what it looks like, I don't know what the blue float at the top is for.

Kenworth 18 · Answer

If I were you, I would replace the drain valve because it prevents the water level from rising and the cistern itself still has a lot of volume to fill it with water.
A higher water level will allow you to remove what you want to remove without any problems.
After replacing the drain valve, you still need to adjust the filling valve so that the cistern fills with more water.

lisu24 · Answer

I replaced the drain pipe, it did nothing. A plumber friend took a look at it and said that the fault probably lies in the design of the compact and only its replacement can improve the situation. As for replacing the drain valve, it may not be visible in this picture, but the tank is filling up almost entirely.

Anonymous · Answer

Make a video from the perspective like in the second photo from post 1. I don't like this valve. Where is the water flow? Typically such valves have channels on the sides.

zjo · Answer

A simple test. Pull out the drain valve, close the drain by hand, fill the tank and unclog. If the flow is ok - the valve needs to be replaced, if not - the problem is lower ...

lisu24 · Answer

It seems to me that I have solved the problem, or at least there is an improvement. As you can see in the first video, after rinsing, the water stream was mostly directed from the side of the tank. After removing the tank, I plugged the hole that directed the water there and now it looks like in the second video. trials is an improvement in flushing.
Thank you all for suggestions and advice.
