This question is regarding Mira Sport Max - Shower Spares

Sport Max intermittent low temp

Sport max 5 ish yrs old - intermittent prob with low temp. switching off then on again usually cures it. Shower has its own circuit and when switching on lights usually dip in the house for a fraction of a second - have noticed that when shower is not running up to temp the dip doesn't happen, suggesting less load - then suddenly the dip and shower then comes up to temp.

The things to check first are.

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water
getting to your shower to open / close the safety device that allowspower through to the elements

 

Make sure that the shower headis clean and clear, that the hose isn’t kinked (this can happen just behind thehand set where it is difficult to see) also check the inside of the hosealthough it can look OK on the outside it could have collapsed internally

If all the above are Ok then you probably have flow valve which is notallowing the correct amount of water into the shower.
