A small tank toilet takes the sewage that far successfully for years to come? It 4" PVC and installed more than 25 years ago. We have had no trouble to this point. Question is this. This toilet is the old large type tank..............which to me, for being a use to be plumber by trade.Memory is "getting cloudy"Saving water is not always the best way. So will the smaller tank toilets.....work just as good. Ihave been told a longgg time ago this will work, But if you plug up a sewer that long could be an expensive trip getting it reamed out, please give me your thoughts from past experinceses thanks bob s

 

That's a long run of 4". Where I live all of our houses drain to 4" cast iron which can run pretty far (40-120ft) before connecting to a larger branch. The inside of the cast iron is not very smooth so I always worry about them. I worry about inside the house too when there's a horizontal run serving a low-flow toilet.

I always like to see other fixtures up the line like sinks and showers to help wash the pipe. Is your toilet the only thing draining into this 270ft sewer?

 

Water and waste have no idea how long the pipe is. As long as it's pitched to keep it moving... it keeps moving.

A modern low flow toilet may show deficiencies or problems in your pipe that are currently being masked by lots of water. If you have a level area in the drain pipe more water may help push the wast through wile a low flow toilet may allow things to settle or not make it through that section. It's not really the toilets fault but it could be a difference.

 

No it isn't ---4" has a 4" y'd in coming in 100 feet , from the main sewer, and she washes clothes every monday, Theres a dishwasher ahead of the flow-- another toilet dumps in to this 4" everyday. How good does this sound.Theres discharge of water in this sewer from showers baths wash bowls kitchen sink i think i answered my own question aayy?/ thanks fellas for your help bob s


ps this sewer is All pvc Out to the tap in.

 

PVC is good. If you are going to a low flow toilet I would not go cheap. There is a huge difference in flush performance between toilets.

 

Dane, I disagree. After a flush, liquids and solids will only go so far in a pitched pipe before the liquids eventually 'outrace' the solids and the solids sit still in the pipe. That's why it's good that other fixtures also drain into the line since they'll supply plenty of liquids to continue moving the solids down. I also think it's good if there's a vertical fall to help break up the solids.

If it were only a toilet draining into a 270' line I'd be worried there simply wouldn't be enough water per day to keep things moving before the solids started sticking to the pipe and drying up and getting stubborn.

A 1.28 gallon flush only has enough liquid to fill 1/138th of the 270' pipe. 1.28 gallons makes a 1/8" bead of water at 270' long.

 

Liquids are more likely to out race the waste in a pipe when it is pitched too much. And your 1/8" assumption is wrong. The waste is like a dam that is being pushed down the pipe by whatever amount of water is behind it.

 

There is A 3' drop ....vertical and sloped properly. just o/s the bathroom wall.The fellow who built our house was phanatic on things being done right.started the house in 66 therabouts,and we finished it in 94.I assume as for his way of doing this piping he would be pretty carefull on its installation.He started building this ranch style house .with 2 sons making their own concrete blocks for the basement walls. One son lives 2 doors down.WAY TO MUCH WORK he found out. thanks all i'll purchase a smaller tank toilet.with confidence now. good week to you all. Bob s
