WORKED EXAMPLE

The example below Is for a G1/2 temperature & pressure relief valve with a

discharge pipe (D2) having 4 no. elbows and length of 7m from the tundish

to the point of discharge.

From Table 2;

Maximum resistance allowed for a straight length of 22mm copper discharge

pipe (D2) from G1/2 temperature & pressure valve is 9m. Subtract the

resistance for 4 no. 22mm elbows at 0.8m each = 3.2m. Therefore the

maximum permitted length equates to: 5.8m. As 5.8m is less than the actual

length of 7m therefore calculate the next largest size.

Maximum resistance allowed for a straight length of 28mm pipe (D2) from

G1/2 temperature & pressure valve equates to: 18m. Subtract the resistance

for 4 no. 28mm elbow at 1 .Cm each = 4m. Therefore the maximum permitted

length equates to: 14m

As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.

WARNINGS

The outlet from the temperature & pressure relief valve must not be used for

any other purpose. This also applies to the expansion relief valve. No other

valve is to be fitted between the cold water combination valve and the

cylinder.

The temperature & pressure relief valve must not be removed in any

circumstances. Any of the above will totally invalidate the guarantee.
