Hi did you run a seperate cold water supply from the storage tank to the shower pump & also a seperate hot supply from the hot water cylinder, it sounds as though the cold water is crossing into the hot service & pushing its way up to the tank as its the only way it can go, sounds as though the cold water connection to the shower is not tank fed & possibly directly off the water main.?

Why do we need to have to continuously adjust the temperature of the water when we're taking a shower. We have a new Rheem gas .hot water tank


It *may* not be a problem with the water heater itself necessarily. When you say "keep adjusting the water temperature when you're taking a shower" I presume you're talking about turning the shower hot/cold knob(s) and not the temp thermostat on the water heater itself.
If so, when it starts to run colder, turn the knob all the way to full hot. Is the water then very hot? If so, the water heater is working fine & doing its job, and the problem is likely to be in the shower faucet mixing valve itself. Sometimes a faulty one will expand the inner seals/cartridge as hot water flows thru it, and starts to (wrongly) restrict the hot water flow, thus causing the constant need to "turn the dial up a notch".

Grohe mixer will only start the pump on cold. Is the unit faulty.


Ive written a solution twice but for some reason it wont let me post it.I will try to abbreviate it.

You dont say how much flow it has when the pump isnt running but I suspect there isnt enough to turn on the sensor unless all the flow is one side. ie all cold.

Installation manual for oak tree stove


No idea here this is not a car question and iam not a plumber but i did have a emersion heater years ago and the cold feed from a header tank in the loft went into the heater and their was two feeds one from the tank and one direct from the mains with a special non return valve in the main line feed --why it didnt just fill from the header tank i have no idea but from that i would say the feed for your heater would be much the same with a header tank in case the inlet supply froze up ? Sorry iam a car mechanic so i have no idea but the return inlet pipe would be my logical choice

Low water pressure


When it was installed was there any copper sweating done? If so, the valve cartridge can get fried if not removed prior to the immense heat from a torch.

I am putting in a new shower and want to put in a pump to increase the flow of water to the shower head,what pump do I need? I will put it next to the hot water cylinder in the airing cupboard,I also want...


First of all, the normal water pressure is anywhere from 50 to 70 lbs. Why do you need a pump? What you need is just water pressure. The shower head will only put out a fraction of that pressure with the valve body inside the head. Since you do not say what water pressure you have, check all the pressure lines to make sure there is no blockage. As for the water tank, well, 50 gallons is always better.

Central heating circulating pump


The vent pipe should be in front of the pump so that the pump pushes towards the vent pipe NOT sucks from it. I hope this vent pipe is part of the heating system and not of the hot water
Pumps like to push not pull and therefore it is better if the pump is located further down - say at the bottom of the cylinder or lower.
With an indirect cylinder, the hot water & heating are separate circuits and are not and must not be interconnected. You will need a separate pump for the hot water which should be taken from the hot pipe coming out of the cylinder. You may get vacuation in the cylinder - then you will need an Essex or similar valve to replace the hot water outlet connection
By the way - The pressure at any hot tap is directly related to the height difference between the tap and the header tank in the loft [thus a shower downstairs feels stronger than one upstairs]

Whirlpool Energy Smart water heater not hot


I think some one mis informed you, the normal temp on any water heater from the factory is 120, it should not go above that for reasons of sevear burns, as far as it't smart part it's just a name, you will lose a couple of degrees just comming torm the tank to the faucets, the water heater will allways keep the temp in the tank at what ever it is set at, it doesn't have the brains or computer to know what time of day it is but when the cold water comes in to the tank it comes thru a dip tube that goes to aprox 1 inch from the bottom of the tank, if you take a long shower and do not have a energy efficant shower head you can use up to 5 gals, per min of hot water where an energy efficant one only uses 2.5 or less and still has the same pressure at the shower head, the temp in your water heater tries to stay at the setting it is at depending on how much is used at one time meaning washing machine, filling tub or dishwasher at the same time, it lets more cold in as the hot goes out and as you know it can only heat up so much at a time and the cold water is just going across the bottom of the tank, so the name is just that no diffrent then any other water heater unless you went to a tankless water heater.
