The water from the loo and shower is rising & not going down

thermostat

There can be various reason of water drizzle, the main reasons are:

1. Low water pressure, it's the main reason for water drizzling. Check the water pressure of your house and if it's loo low then fix it.

2. Rust in your shower head, if your shower heads is full of rust it can be a reason for water drizzling. Clean your shower head nicely to remove those.

Thanks.

I do not know how old this unit is or what model but many water heaters are not sophisticated enough to measure the temperature, but heat based on water flow and temperature rise. To start, tankless water heaters turn off every time you turn the hot water off. Lets use an example. You use the facilities, wash your hands then turned off the water and take a shower. You will bring the already heated water (from washing your hands) from the pipe up to the shower. Then the cold water that comes into the pipe from the reactivation of the water heater comes up the hot water pipe with warm then hot water just behind.

If this is not your problem, keep reading. Every unit I have been called to see were installed wrong. Check your installation manual to see if the problem with the system started with the contractor.

First, check the temperature of the water from the heater. If it is too hot and you are mixing too much cold water in, the unit will turn off because there is not enough water flow to keep it running.

Second, turn off the valve at the water heater and turn on the hot water at a faucet. If the water does not stop running, there is a "plumbing cross over" usually caused by a failing pressure balance valve in a shower.

Third, if the unit has not been serviced, go to bosch-climate.us to find a tankless water heating professional in your area. Totally Tankless LLC

Obviously the drain line from your toilet to main drain out of the house ( used by upstairs ) has a blockage from your toilet line to "Y" in to main drain line. Depending on how it has been plumbed, there may be a clean-out between the 2 that can be used to remove the blockage. Your drain for shower is piped in to same line as toilet, thus when blocked at other end, overflows to shower. You can try some drain cleaner down shower drain if it will go. You might get lucky and release the blockage before plumber shows up .

here are the instructions for your faucet go down to the adjust temp stop limits section, and your home free Good Luck http://www.moen.com/shared/pdf/instruction_sheets/mt692c.pdf

You did not tighten the stem enough, allowing the seat to rise just above the cavity where it will sit. You may also have scaling in this area preventing the seat from sitting flush.

We have a maserator in en-suite which serves the toilet & shower, We moved in to house 6 years ago and it was already here. After having guests stay a couple of months ago the maserator hasnt worked properly. When we flush the toilet, the water rises and whilst the cistern is filling with water, there is a humming noise for a couple of minutes, then the water rushes back down and there is a clonk and the water bubbles back up through the shower plug hole.Any suggestions as to what this problem is & how to fix it please?

The only possible explaination is that the water is finding it easier to go up than down. Water is lazy, just like me. ;)

Use an allen key to remove the tub spout. It's underneath and awkward. Once the allen key is loose, the spout just slides off. Try running the water. This may solve your problem and all you'll need is a new tub spout. If not.....

Turn the water off to the house.

Use an allen key to remove the handle.

Use a phillips to remove the trim plate (2 screws). Cut the silicone around the trim if it's there (which, in a proper installation it shouldn't be, but...)

Unscrew the nut (usually chrome) holding the cartridge into the brass body of the valve. The cartridge pulls straight out. Check for restriction in the ports of the cartridge itself. Check for restriction in the line going down to the tub spout. If you can't find anything, replace the cartridge.

Reassemble & Enjoy!

You must of turned off your water to the house or maybe it was turn off in the street recently because it sounds as if you have debris in you strainer remove the head and rise of removing any dirt rise out both front and back of shower head while head is off run shower to make sure you are getting full pressure out of the pipe that the head is connected to
